海外TECH DEV Community Toggle dark mode of a page in a blink https://dev.to/theankurkedia/toggle-dark-mode-of-a-page-in-a-blink-279m Toggle dark mode of a page in a blinkThis article is about how you can add blink detection in your project using TensorFlow js As an example we will toggle the dark mode on a page It s just a fun project to get started with Machine Learning and TensorFlow js Here is the result Sorry your browser does not support embedded videos What should you know before starting Well nothing as such In simple terms you can think of TensorFlow as a library that infers patterns from data and identify those patterns when they occur You can either use pre trained models or train your models with Teachable Machine Let s get started and set up a TensorFlow js projectLoad model You need to load the model to be able to use it In this case we are using face landmarks detection model import as faceLandmarksDetection from tensorflow models face landmarks detection import as tf from tensorflow tfjs core import tensorflow tfjs backend webgl const loadModel async gt await tf setBackend webgl model await faceLandmarksDetection load faceLandmarksDetection SupportedPackages mediapipeFacemesh maxFaces Setup camera To detect the face the model needs a video stream We will create a video element and pass its stream to estimate features on the face const setUpCamera async videoElement gt video videoElement const mediaDevices await navigator mediaDevices enumerateDevices const defaultWebcam mediaDevices find device gt device kind videoinput amp amp device label includes Built in const cameraId defaultWebcam defaultWebcam deviceId null const stream await navigator mediaDevices getUserMedia audio false video facingMode user deviceId cameraId width height video srcObject stream video play video width video height Start estimation For estimation we will have to continuously monitor the face and keep checking if the user is blinking or not const predictions await model estimateFaces input video returnTensors false flipHorizontal false predictIrises true This returned prediction is an array of objects with values likefaceInViewConfidence boundingBox mesh scaledMesh annotations The facemesh keypoints can be obtained from the annotations key These were the common steps you will need to do to set up a TensorFlow js project with the face landmarks detection model If all goes well the browser should ask for camera permission when you run the project to be able to detect live video and once the model is loaded it starts predicting Adding blink detectionWith the keypoints we can calculate the Eye Aspect Ratio EAR with the following formula EAR p p p p p p Here d represents the Euclidean distance which is essentially the length of a line segment between the two points And the points p p and so on used here are mapped on the facemesh in the image So when the person blinks the EAR will drop close to zero To detect the blink the EAR will have to be lesser than a threshold which is close to zero So I used an EAR threshold that works for varying distances between the user and the camera Once the EAR drops below the threshold we know that eye is blinked We have separate keypoints for both the eyes so we can detect both eyes blink separately To the dark sideSome time back I read about an easy way to force the dark mode which uses the CSS filter property Coupling it with the color scheme property we can add dark mode to a majority of the pages So I would add these CSS properties to the root HTML element filter invert hue rotate deg color scheme dark Note There are some caveats to this method But this works well enough for us to learn the basics And hey you get the dark mode with two lines of CSS Which I think is pretty cool Blink DetectionTo be able to reuse the logic I created an NPM package named Blink Detection which does the calculations and returns the result import blink from blink detection const blinkPrediction await blink getBlinkPrediction Here the blinkPrediction will be an object with the keys blink wink longBlink left right rate Each key except rate will be a boolean value ChallengesWith the face landmarks detection model you will need to manually map facemesh keypoints on a graph from the data readings There are a lot of annotations that can be used but I could not find any source explaining them To decide the EAR Eye Aspect Ratio threshold I had to try different values I use the one that works the best for different distances between the user and the camera So it is not bullet proof More ideas with blink detectionChrome extension You can create a chrome extension for the same demo Another extension idea is to gauge the eye blink rate and use it for different purposes Blink rate There have been numerous studies on how blinking patterns can measure or apprise certain aspects of an individual or a situation Wink detection Similar to blinking wink detection can also be used to perform some actions Wrapping upThat s it Overall this project wasn t really about toggling dark mode I wanted to play around with TensorFlow and create something while doing it Also I could not find any project related to blink detection in Javascript so I developed the package Check out the demo and the code theankurkedia blink detection Detect the user s blink and wink using machine learning ReferencesI found the following resources helpful If you want to experiment and create something similar you can start here Pre trained TensorFlow js models for different use cases If you are using the face landmarks detection model the facemesh keypoints can help you map the points needed for your use case This amazing project was a great starting point Honestly I just cloned the repo and started experimenting TensorFlow js object detection Codelabs Teachable Machine to train your models Eye blink detection with OpenCV Python and dlib Thanks for reading Hope you found it helpful Happy

海外TECH DEV Community OOP Series: Abstraction and Interface In Java https://dev.to/princeibs/oop-series-abstraction-and-interface-in-java-104g OOP Series Abstraction and Interface In Java INTRODUCTIONAbstraction is one of the four basic principles of Object Oriented Programming OOP It enables us to give structure to our programs and applications Abstract classes are used to create structure or design in which all other subclasses must follow Consider a smartphone for example smartphones have a screen that the user can touch to interact with the phone Other properties of the smartphone are camera speaker battery earphones buttons etc and a smartphone can do some things like play music make a call receive a call take pictures videos etc Considering some models of phones like Android iOS Blackberry etc An android phone for instance must at least be able to make a call receive a call and browse the internet before we can consider it a smartphone For us to consider Android iOS and Blackberry in the class of phones they must also be able to perform the basic functionalities listed above Then can we conclude that we have abstracted Android and iOS from the Phone CONTENTPrerequisiteAbstractionAbstract class and Concrete classAbstraction vs EncapsulationCode ExampleInterface Properties of InterfaceCode exampleConclusion PREREQUISITEBasic understanding of OOP Methods Classes and ObjectsSome OOP principles Inheritance Encapsulation ABSTRACTIONAbstraction in Java is the process of creating abstract classes and methods which define the structure of subclasses We can achieve abstraction in Java by adding the keyword abstract to a class declaration name and providing abstract methods to the class It is also achieved using interfaces and abstract classes An abstract method is an instance method that is declared with the keyword abstract and does not have a body i e it is delimited by a semicolon public abstract void testMethod Below are some of the properties of an abstract class You must declare it with the keyword abstract Classes declared without the abstract keyword but containing at least one abstract method will throw a compilation error It cannot be instantiated We cannot create objects of the class using the new keyword All subclasses inheriting from the abstract class must provide an implementation for the superclass abstract methods It can be sub classed Abstract classes can also act as a subclass and inherit the properties of a superclass It can contain zero or more abstract methods It can contain concrete methods Concrete methods are methods with a body and implementation unlike abstract methods that are delimited by a semicolon and do not provide an implementation All other members of the abstract class like instance variables and concrete methods continue to abide by the rules of inheritance Subclasses handle them as they will for other concrete classes Abstract class and Concrete classAn abstract class is any class declared with the keyword abstract and contains some abstract methods Some of the properties of the abstract class are listed above A concrete class is somewhat opposite to an abstract class A concrete class is a class that is not declared with the keyword abstract and does not contain any abstract method While an abstract class cannot be instantiated a concrete class can be instantiated Meanwhile a concrete subclass inheriting from an abstract superclass must implement all of the superclass abstract methods otherwise the subclass must also be declared as an abstract class Abstraction Vs EncapsulationYou can achieve encapsulation without abstraction but cannot achieve abstraction without encapsulation Abstraction and encapsulation are two of the most misused concepts of OOP Abstraction focuses on the design of the object in focus while encapsulation focuses on the implementation The key to understanding the difference between the two isAbstract all the things you needand Encapsulate all the things you don t need Consider a car for example some of the basic necessities of a car are the steering wheel accelerator pedal brake pedal gear selector etc Since a car needs all these things to be classified as a car we can conclude that these things are being abstracted from the car This is because a car can t do without them But the functionalities of these parts of the car are not made visible to the driver and the driver does not need to know how the steering wheel rotates the tire or how the accelerator and brake pedal controls the speed of the car This is known as encapsulation The implementation and the details of these parts are hidden from the driver so the driver only interacts with the few parts made available by the car like the parts listed above In this case we are hiding the complexities from the driver which is encapsulation Code ExampleThe three programs below explain the concept of abstraction in Java using three classes The Phone abstract class and two other concrete classes the Android class and IOS class The Phone ClassThe image depicts the Phone class hierarchy The Phone class is blurred in the image to signify it is an abstract class package Abstraction public abstract class Phone private String color private String brand initialize instance variables public Phone String brand String color this brand brand this color color set and get methods public void setColor String color this color color public String getColor return color public void setBrand String brand this brand brand public String getBrand return brand abstract methods public abstract void makeCall public abstract void receiveCall public abstract void browseInternet overrides Object s method Override public String toString return String format s specs getBrand The Phone class starts by adding an abstract class declaration in its signature with the keyword abstract This is the default syntax for declaring a class as abstract in Java The class moves on to declare its instance variables and then to the constructor used to initialize these variables followed by setters and getters methods used to access and modify these instance variables The next set of methods includes the abstract methods makeCall receiveCall and browseInternet that demonstrates the must have of a smartphone This is similar to the smartphones we use in real life most smartphones perform these three basic functionalities Every other type of phone inheriting the properties of our Phone class must be able to make a call receive a call and browse the internet The implementation of these methods might vary but functionality must be the same One thing to note here is that the Phone class contains concrete methods with implementations along with its abstract methods The next two classes will be inheriting these properties of the Phone class The Android Classpackage Abstraction public class Android extends Phone private String version android version public Android String color String brand String version super color brand initialize superclass variables this version version initialize instance variable set and get methods public void setVersion String version this version version public String getVersion return version abstract methods implementation Override public void makeCall System out println Calling with Android System out println Call ended Override public void receiveCall System out println Calling with Android System out println Call ended Override public void browseInternet System out println Browsing with iPhone System out println Session ended Override public String toString return String format s nVersion s nColor s n super toString getVersion super getColor The Android class like any other regular subclass class inherits from a superclass which is the Phone class using the keyword extends similar to inheritance in its class declaration It includes an instance variable and a constructor to initialize the variable then the setter and getter method to manipulate the variable Our focus here are the methods makeCall receiveCall and browseInternet They override the superclass methods using the Override annotation Here the Android class must override these abstract methods and provide implementation a body in order to be called a concrete method This is because the Phone class it is inheriting from contains these abstract methods This is very useful in designing smartphones in real life where each smartphone has a basic requirement they must meet Because of these design constraints users won t be overwhelmed by the variations of smartphone design each brand is producing The IOS Classpackage Abstraction public class IOS extends Phone private int camera number of camera public IOS String color String brand int camera super color brand initialize superclass variables this camera camera initialize instance variable set and get methods public void setCamera int camera this camera camera get the number of camera public int getCamera return camera abstract methods implementation Override public void makeCall System out println Calling with iPhone System out println Call ended Override public void receiveCall System out println Receiving call with iPhone System out println Call ended Override public void browseInternet System out println Browsing with iPhone System out println Session ended override Object s method Override public String toString return String format s nColor s nNumber of Camera d n super toString super getColor getCamera The IOS class above is similar in structure to the Android class It contains an instance variable a constructor to initialize the instance variable and a setter and getter method to manipulate the instance variable The main difference between the Android class and the IOS class is the implementation of the inherited abstract methods In this case both have similar methods and prints different message which in real life it might be some block of code with actual functionalities But for the sake of this article we are keeping things simple by printing some text to the console Now if a user is to transition from an IOS to an Android device they won t be much difference in the functionalities of the two devices Because from the onset both share the same design This is another good advantage of abstraction in the real world The PhoneTest Classpackage Abstraction public class PhoneTest public static void main String args create objects Android android new Android Android Diamond Black IOS ios new IOS iOS Pale Blue display objects System out println android System out println ios perform action with objects android makeCall System out println white space ios receiveCall We use the PhoneTest Class above to test the implementation of the three classes created above Phone Android and IOS class It starts by creating objects of both the Android and IOS classes and initializing their instance variables by passing the values into their constructor call The next set of statements display the string representation of the respective objects created above Note that we printed the objects without any helper methods but rather with the help of the toString method overridden inside each class It helps to display objects of that class in a custom way The next statements perform some actions with the objects by making a call with the android object and then receiving a call with the ios object and the implementation of each method is printed in the console Below is the output of executing the PhoneTest class INTERFACEInterface specifies what to do and not how to do it An interface in Java is a type that contains static constants and abstract methods and defines the behavior of classes Interface is an extreme case of abstraction and is used to achieve abstraction This implies that interfaces cannot contain concrete methods and all the abstract methods it contains must be implemented by the concrete subclass Interface comes into play when classes that are not related need to share a common design This happens when we need objects of different classes to respond to the same method call Interface in Java acts as an interface between different classes sharing a common design Consider the TV remote control for example most remote control contains at least one button so if a particular model brand of remote control is to implement the remote interface it must contain at least one button because the default design of a remote includes at least one button Properties of InterfaceSimilar to abstract classes interfaces cannot be instantiated An object of an interface cannot be created using the new keyword All fields in an interface are implicitly public static and final Interface cannot have concrete methods Interface cannot extend other classes All methods in an interface are implicitly public and abstract methods A class must implement all of the methods of an interface otherwise it must be declared abstract Interface can extend but cannot implement other interfaces A class can implement multiple interfaces This is done using a comma separated list of interfaces after the keyword implements in the class declaration public class className extends superClassName implements interface interface interface Code ExampleThe code snippets below explain the concept of interfaces in Java The Camera Classpackage Abstraction public interface Camera public void takePicture public void flashlight The program above contains an interface Camera that has only two methods As seen from the program the class declaration includes the keyword interface they are no concrete methods here because interface in Java does not accept it The methods that this interface has included some of the basic functionalities of a camera So any class that wants to implement a Camera interface must be able to take a picture and includes a flashlight at least Modification to the Android ClassThe two snippets below modify the Android class to implement the Camera interface public class Android extends Phone implements Camera The snippet above implements the Camera interface using the Android class by adding the keyword implements followed by the name of the interface to implement in this case Camera is the interface to implement This is the default syntax for implementing an interface in Java In real life for an Android phone to have a camera interface it must be able to take pictures along with a flashlight this is exactly what our Camera class is doing here enforcing the Camera design on Android overridden interface methods Override public void takePicture System out println Taking picture System out println Picture taken Override public void flashlight System out println Flashlight is turned on System out println Flashlight is now off The snippet above shows another modification done to the Android class All other parts of the program remain the same except for these two methods added to the class because of the interface the class is implementing The two methods above provide implementation to the takePicture and flashlight methods in the Camera interface As seen from the properties of an interface all of the methods must be implemented in the Android class else the compiler will throw an error android flashlight The above line of code was added to the phone test class to demonstrate one of the methods the Android class is implementing Below is an output of running the PhoneTest class with the modifications done to the android class The output above remains similar to the first output except for the last two lines that display the output of implementing the flashlight method ConclusionThis article starts by introducing the concept of abstraction in Java and its properties as well The knowledge of Abstraction is a very valuable concept in OOP and programming as a whole because of its numerous advantages and applications in the real world Interface on the other hand is an extreme case of abstraction Most software engineers encourage the use of interface as it helps to preserve design and also helps in modeling software This article briefly introduces the concept of abstraction and interface in Java Visit the official Java documentation to know more about the concepts discussed here 2021-11-09 07:19:01
海外TECH DEV Community How To Master Python https://dev.to/abstract/how-to-master-python-4l79 How To Master PythonPython is one of the most popular and friendly programming languages I learn Python myself a few years ago and it was my first programming language too however there weren t any roadmaps or quick tutorials courses on how to learn Python That s why I provide you these top tips that helped me and will help you of learning not only Python but any other subject that you want At the end of this article I ll leave a link to my roadmap that I built for you where you can find all sites book courses which I will tell you about in this article Understand WhyFirstly you need to know why you want to learn Python and whom you want to become when you will already know Python The reason like I want to learn Python because it s easy actually not so easy and earn millions of dollars per year That doesn t work so When I just started learning Python I really enjoyed the idea of automating everything and building your own robot or AI Find something that will inspire you and if it s not Machine Learning Automatization Web or other things that you can easily do with Python then it s not your language When you are completely sure that you need to learn Python and you understand why then this will give you an accurate idea in which direction you should move and help you not to lose motivation to study it Learn How to LearnAs I said some of these tips will help you not only with Python Learning how to learn is a very common part you should define which way of learning is better for you for instance watching YouTube videos course read books or other ways Actually they will all be used in some amount but basically you should study the method that suits you best especially I watch videos or courses FundamentalsIf you won t get the fundamentals of Python you also won t get more difficult things like Data Science It s obviously the easiest part of learning Python just watch some Crash Course of Python on Udemy Coursera Codecademy or read Python Crash Course Automate the Boring Stuff with Python of course you can learn from your own sources There s the list of Fundamentals that you should learn first VariablesOperatorsIf ElseLoopsFunctionsData TypesClasses and ObjectsMake sure you understand all of these points PracticeIf you ve read tons of books and watched tons of courses but still don t understand how to write a function that will sort your array list that you need way more practice Hopefully for you there re many sites where you can find problems that you should solve and not only Even if you know how to sort your array then practice at such sites as Codewars HackerRank LeetCode TopCoder etc on these websites you can train your muscle memory to write faster easy code and train programmer thinking Algorithms and act Also you can help other people to solve their problems at StackOverflow   If you want to master Python then you should integrate practice into your daily routine it s useful only where you do it repeatedly Diving into CommunityYou need to understand that you actually can t do anything alone anyway for big projects you ll need some group of people that will help you and inspire you even such companies as Google and Apple weren t build by only one person It means that you should know where to get new programmer friends In a nutshell you can just join the Discord Server of Python and just talk to other programmers or when you are stuck at the problem at Codewars you can easily ask for help and solve this problem with someone else Another way to find new friends is to take part in different ways of Hackathons Libraries and FrameworksSoon as you learned all basics and have more hours of practice and can easily write some sort of algorithm then you should learn Libraries and Frameworks in the direction in which you want to develop further as I said earlier it can be Machine Learning Automatization or Web Development There s top of the most popular and effective Frameworks that you should learn Top Machine Learning Frameworks To Use in Best Python Frameworks and many others Share Your KnowledgeIf you ever hear of Richard Feynman that you probably know that he had a technic that helped him to learn everything and to reach truly amazing heights in physics and not only if you want to understand

ThoughtsProgress and development take place to improve our living conditions In terms of technology changes happen because we want to find solutions to our current problems and no code is a solution for many who don t know how to program or write codes manually The idea of no code is something we shouldn t be taking too much verbally The world has been coding and learning to code day by day and with that there is a massive amount of code already written But that doesn t mean modifications are not needed We still need someone to code regardless One might arrive at a logical conclusion that no code is the future One way or another the possibility of getting there is probable but essentially it will take some time To reach an age of absolute no code we need to outdo ourselves with artificial intelligence before anything else Once we discover how to create programs that can create a program of its own written codes will endure in the future How about you What do you think of no code as the future of website building Until next time Kyle 2021-11-09 07:13:22
