海外TECH	DEV Community	Python: The Best Image Processing Libraries	https://dev.to/imagescv/python-the-best-image-processing-libraries-1gfl	Python The Best Image Processing LibrariesIn this blog post we will take a look at some of the best image processing libraries in Python We ll spend time looking at their strengths and weaknesses to help you pick one that is right for your needs OpenCV The Open Computer Vision library or simply OpenCV is a collection of powerful image processing tools It was originally developed for use in the video game industry but has since found widespread success outside of it as well If you are looking for an open source alternative to MATLAB then this might be your best bet Matplotlib The matplotlib library is a plotting library for Python It can be used to generate plots in either the matlab style or the more traditional gnuplot style depending on your preference Best of all it s actually built into numpy simply use np imshow and youj ll be on your way Numpy While not exactly an image processing library numpy is one of the most important libraries for scientific computing in Python today It provides powerful tools like linear algebra and Fourier transforms that make it easier to work with images If you are doing serious mathematics or data analysis with your images then this is probably the library you want to use ImageMagick ImageMagick is a software suite for processing images It has its own programming language that allows users to manipulate their image files in many ways including resizing adjusting color balance or applying filters and effects Image processing with ImageMagick can be done from the command line or through a graphical interface Pillow The Pillow library is a fork of the PIL library that aims to be more user friendly and maintainable It includes many of the same features as PIL but also adds support for animated GIFs JPEG files and WebP images If you are looking for a drop in replacement for PIL then this is probably your best bet Scikit image The Scikit image library is a collection of image processing algorithms that are designed to be easy to use and understand It includes algorithms for common tasks like edge detection feature extraction and image restoration If you are just starting out in image processing then this is a good library to check out That s it for our roundup of the best image processing libraries in Python We hope this gives you a better idea of which one is right for your needs If you have any questions feel free to leave a comment below images cv provide you with an easy way to build image datasets K categories to choose fromConsistent folders structure for easy parsingAdvanced tools for dataset pre processing image format data split image size and data augmentation Visit images cv to learn more	2021-12-12 20:48:34
海外TECH	DEV Community	Sentiment Analysis With 🐍. Making Your First Sentiment Analysis Script.	https://dev.to/code_jedi/sentiment-analysis-with-making-your-first-sentiment-analysis-script-4ea8	Sentiment Analysis With Making Your First Sentiment Analysis Script Do you want to perform sentiment analysis with Python but don t know how to get started Not to worry In this article I ll demonstrate and explain how you can make your own sentiment analysis app even if you are new to Python What Exactly Is Sentiment Analysis If you ve been following programming and data science you ll probably be familiar with sentiment analysis If you re not here the definition The process of computationally identifying and categorizing opinions expressed in a piece of text especially in order to determine whether the writer s attitude towards a particular topic product etc is positive negative or neutral Sentiment analysis programs have become increasingly popular in the tech world It s time you make one for yourself EducativeBefore I get on with the article I d like to recommend Educative for learners like you Why Educative It is home to hundreds of development courses hands on tutorials guides and demonstrations to help you stay ahead of the curve in your development journey You can get started with Educative here Making A Simple Sentiment Analysis ScriptLet s make a simple sentiment analysis script with Python What will it do It will Scrape news headlines from BBC news Get rid of unwanted scraped elements and duplicates Scan every headline for words that may indicate it s sentiment Based on the found words determine each headline s sentiment Aggregate the headlines into different arrays based on their sentiment Print the number of scraped headlines and number of headlines with a positive negative and neutral sentiment SetupCreate a new Python file with your favorite text editor You can name it however you want but I ll name the file main py for this tutorial Before writing the main code make sure to install if not already installed and import the following libraries import requestsimport pandasfrom bs import BeautifulSoupimport numpy as np The DatasetA sentiment analysis script needs a dataset to train on Here s the dataset that I made for this script I ve tested it and found it to work well To work with this tutorial make sure to download this dataset move it into your Python file s directory and add the following code to your Python file df pandas read csv sentiment csv sen df word cat df sentiment If you take a look at this dataset you ll notice that it s just over lines long Each line contains a number or and a word The number just gives a way for the Python file to paddle through each word the word is what is going to indicate a headline s sentiment and the or indicates whether the word has negative or positive sentiment This isn t a lot but it is enough to perform accurate sentiment analysis on news headlines which are typically only about words long Scraping The News HeadlinesHere s the code that is going to scrape the news headlines url response requests get url soup BeautifulSoup response text html parser headlines soup find body find all h As this is not a web scraping tutorial you don t have to understand what s happening here In case you are interested in how this works here s a tutorial on how to scrape news headlines with Python in lt lines of code Before performing sentiment analysis on the scraped headlines add the following code to your Python file url response requests get url soup BeautifulSoup response text html parser headlines soup find body find all h unwanted BBC World News TV BBC World Service Radio News daily newsletter Mobile app Get in touch news The unwanted array contains elements that will be scraped from BBC news that are not news headlines Full Code import requestsimport pandasfrom bs import BeautifulSoupimport numpy as npdf pandas read csv sentiment csv sen df word cat df sentiment url response requests get url soup BeautifulSoup response text html parser headlines soup find body find all h unwanted BBC World News TV BBC World Service Radio News daily newsletter Mobile app Get in touch news Performing Sentiment AnalysisIt s time to write the code which will perform sentiment analysis on the scraped headlines Add the following code to your Python file neutral bad good for x in headlines if x text strip not in unwanted and x text strip not in news news append x text strip Here s what this code does First it defines the neutral bad and good arrays While paddling through every scraped headline element it checks if it s not inside the unwanted and news array It appends the headline to the news array The reason why it checks if the headline is in the unwanted and news array is to exclude non headline elements and prevent duplicate headlines to be analyzed more than once Full Code import requestsimport pandasfrom bs import BeautifulSoupimport numpy as npdf pandas read csv sentiment csv sen df word cat df sentiment url response requests get url soup BeautifulSoup response text html parser headlines soup find body find all h unwanted BBC World News TV BBC World Service Radio News daily newsletter Mobile app Get in touch news neutral bad good for x in headlines if x text strip not in unwanted and x text strip not in news news append x text strip Now let s perform sentiment analysis on the news headlines by adding the following code to the if x text strip not in unwanted and x text strip not in news condition for i in range len df n if sen i in x text strip lower if cat i bad append x text strip lower else good append x text strip lower Here s what this code does First the for i in range len df n loop makes sure to search the headlines for any of the words in the sentiment csv dataset If a word from the dataset is found in the headline using the if sen i in x text strip lower condition the if cat i condition then finds if the found word has a negative or positive sentiment and adds the headline to either the bad or good array The lower function converts all the letters inside the headlines to lowercase This is done because the word search algorithm is case sensitive Full Code import requestsimport pandasfrom bs import BeautifulSoupimport numpy as npdf pandas read csv sentiment csv sen df word cat df sentiment url response requests get url soup BeautifulSoup response text html parser headlines soup find body find all h unwanted BBC World News TV BBC World Service Radio News daily newsletter Mobile app Get in touch news neutral bad good for x in headlines if x text strip not in unwanted and x text strip not in news news append x text strip for i in range len df n if sen i in x text strip lower if cat i bad append x text strip lower else good append x text strip lower There s one thing left to do Add the following code to the end of your Python file badp len bad goodp len good nep len news badp goodp print Scraped headlines str len news print Headlines with negative sentiment str badp nHeadlines with positive sentiment str goodp nHeadlines with neutral sentiment str nep This will print the number of scraped headlines and the number of headlines with a bad good and neutral sentiment The End ResultHere s the full sentiment analysis code import requestsimport pandasfrom bs import BeautifulSoupimport numpy as npdf pandas read csv sentiment csv sen df word cat df sentiment url response requests get url soup BeautifulSoup response text html parser headlines soup find body find all h unwanted BBC World News TV BBC World Service Radio News daily newsletter Mobile app Get in touch news neutral bad good for x in headlines if x text strip not in unwanted and x text strip not in news news append x text strip for i in range len df n if sen i in x text strip lower if cat i bad append x text strip lower else good append x text strip lower badp len bad goodp len good nep len news badp goodp print Scraped headlines str len news print Headlines with negative sentiment str badp nHeadlines with positive sentiment str goodp nHeadlines with neutral sentiment str nep Now if you run your Python file containing the above code you will see an output similar to the below ConclusionI hope that this tutorial has successfully demonstrated how you can perform sentiment analysis with Python Byeeee	2021-12-12 20:22:14
