海外TECH	DEV Community	Around the World with Amazon Rekognition Image	https://dev.to/aws-heroes/around-the-world-with-amazon-rekognition-image-2d1m	Around the World with Amazon Rekognition ImageThis is the first article of a two part series playing with Amazon Rekognition and flags from around the world Today we will focus on testing the default behavior of Rekognition Image in the second part we will use Rekognition Custom Labels to build a custom machine learning model and detect national flags Rekognition ImageObject and scene detection is a key feature of Rekognition Image and a powerful and useful technology to search and filter large image collections It is possible to build applications to search and organize images assigning labels based on the visual content According to the documentation The DetectLabels API lets you automatically identify thousands of objects scenes and concepts and returns a confidence score for each label DetectLabels uses a default confidence threshold of Rekognition supports thousands of labels belonging to common categories Will it recognize a flag Can we use the service to map and search national flags The AWS Management Console offers a very good “try demo option that works for any jpeg or png image no larger than MB Let s give it a try uploading a photo I took at the Haus der Kulturen der Welt in Berlin last week Good news The label “Flag is definitely supported by Rekognition Image and the confidence is very high Labels Name Flag Confidence We can move to the next step testing different flags National flagsWhile learning the implications of software in disputed territories and partially recognized countries I encountered a simple case for image detection national flags How can we test them with Rekognition Image First of all we need some images a reliable dataset we can use to test the behavior of the managed service As a dataset of regional and national flags we will use the ones from the open source repository region flags a collection of flags for geographic region and subregion codes maintained by Google Graphic images of flags are not the only option or even the main testing scenario there are also photos with flags For real pictures where a flag is present we will rely on Unsplash a sharing stock photography website with a liberal license We might test automatically the entire region flags dataset later on using the SDK but for now we can start manually with a few selected countries and the management console The Stars and StripesThe obvious benchmark is the flag of the United States of America It should be an easy one to be detected given that it is likely the main market for the product and the initial dataset for training Amazon Rekognition labels it as a “Flag with a confidence and “American Flag with a confidence A good and reliable result But is it enough to trust the service for labeling flags worldwide How does Amazon Rekognition perform when we analyze real pictures including the Stars and Stripes Let s add a second photo from Unsplash They have a confidence of and for the American Flag The value drops to if we instead choose a flag in a less common position Not ideal but the confidence is still pretty good all three images score between and Can we then set our confidence at and not validate further the responses Time to move to different countries to understand how Rekognition works what the confidence level represents and avoid side effects Amazon this is not the Stars and Stripes Let us cross the Florida Straits and use the flag of Cuba Some similarities in colors and patterns but it is a very different flag and country The confidence level for the label flag is still very high but surprisingly Rekognition scores for the American flag Is it a glitch or a side effect of similarities in shape and design Is the model not trained Il TricoloreAs an Italian cloud architect the natural choice for a completely different flag is il Tricolore different colors different patterns But at the confidence for the label American flag is even higher than for Cuba What is going on here Let s try a real picture not just a graphic of the national flag Rekognition is doing an amazing job detecting both flags in the photo but it is not able to recognize them as Italian ones It is labeling them as American ones The American flag or the Malaysian one We could compare many other national flags but the results would be very similar Most are correctly labeled as flags almost all the ones with distinct stripes but they are labeled as well as American flags with different levels of confidence No other national flag label is detected neither an “Italian Flag nor a “Cuban Flag Amazon Rekognition uses a hierarchical taxonomy of ancestor labels to categorize labels but apparently the only child of “Flag is “American Flag Name American Flag Confidence Instances Parents Name Flag Name Symbol The closer a flag resembles the Stars and Stripes the higher the confidence level for the flag of Malaysia the value is very similar to the one of the United States Setting an arbitrary high confidence level might help reduce failures but it is not the strongest safety net for flags We have a surprisingly similar result if we take a Malaysian flag from Unsplash with a confidence for the American flag that is even higher than the one we saw for the real flags of the United States that scored between and Not a flagMapping any flag to one of the United States is only part of the issue Other images instead might raise questionable labels For example the Bandeira de Portugal might be a positive result when your users search for dynamite weapon bomb or weaponry all labels with a high confidence level Flag is not in the top labels as the PNG file is not recognised as a flag The Portuguese flag performs better in a real scenario where it is once again labeled as flag with a confidence level of Anything new The above results have been consistent testing Rekognition Image in the last two years but I wanted to check if something changed recently Given the on going war in Ukraine and the popularity of the Ukrainian flag in the last four months I checked how Amazon Rekognition detects it The results are very similar to the Portuguese ones The flag itself is not recognized as such with labels that are way off topping with “Home Decor Once a real picture is used it is labeled as a flag with a high confidence above but again no match for the country Any feedback from Amazon The first time I noticed the issue I raised a ticket to AWS Support and the feedback was straightforward I was in touch with the Rekognition engineering team as well as the Rekognition product team and I have relayed your message over to them They acknowledged that Rekognition is currently not trained to identify the flags That is fair but I would then recommend removing the value “American Flag until it is the only child of “Flag it gives little benefits with mostly false positives in non US scenarios ConclusionsWhat have we learned so far Is it worth using Rekognition Image Rekognition Image is doing a good job in decoding objects as flags in photos in very different conditions It is not able instead to recognize different flags and it is labeling incorrectly most of the objects as American flags Accuracy is always relative Setting an artificial confidence level for the results of Amazon Rekognition is not enough National flags are not the most important label and training scenario for machine learning but they are an example of the challenges when image detection is not handled properly This is not an AWS problem this is our problem as developers integrating a managed service like Rekognition Image in our product or service You will be the public face for your end users If you need to integrate image recognition capabilities in your application you have to manage the risks and challenges yourself If you need more reliable data you need to take the next step in the image detection journey Next step It is now time to take the problem in our own hands and train a model to better recognize flags How can we achieve that with Rekognition Custom Labels How is Amazon Rekognition going to perform We will discuss that in a separate article Thanks for making it this far I am always looking for feedback to make it better so please feel free to reach out to me via LinkedIn or email CreditsAll the photos and images from the author Unsplash or the region flags repository You can find more on cloudiamo

海外TECH	Engadget	DJI's RS3 mirrorless camera stabilizer unlocks automatically and is easier to balance	https://www.engadget.com/dji-rs-3-mirrorless-camera-stabilizer-is-easier-to-balance-than-ever-133529755.html?src=rss	DJI x s RS mirrorless camera stabilizer unlocks automatically and is easier to balanceDJI has significantly expanded its gimbal lineup with the RS and RS Pro models designed for mirrorless and cinema cameras It also launched some other interesting cinema products derived from the innovative Ronin D camera gimbal including a LiDAR focusing system and DJI Transmission for remote monitoring and control of compatible gimbals Finally it announced that it has joined Panasonic and Leica s full frame L Mount alliance and unveiled a compensation for removing ProRes RAW from the Ronin D nbsp DJI s flagship mainstream gimbal is now the DJI RS The key new feature over the RSC is an automatic locking system that releases and unfolds the gimbal when it s turned on then folds and locks it when turned off That avoids the usual dance of steadying the camera by hand when turning off the gimbal then manually locking three separate axes nbsp DJITapping the power button sends it into sleep mode which makes powering on the device stowing it away and relocating much faster DJI notes It also uses quick release plates for position memory so in theory you only have to balance your camera once nbsp It weighs in at just under pounds but can handle a payload of pounds enough to support most mainstream mirrorless cameras The rd generation stabilization algorithm offers a percent improvement over the RSC so it s easier to shoot low angles running or filming from a moving vehicle For longer lenses up to mm SuperSmooth provides further electronic stabilization nbsp DJIIt has a Bluetooth shutter button that supports automatic connection without the need for a camera control cable along with a inch full color OLED display with percent more surface area than the RSC That screen allows a full gimbal setup in most scenarios without connecting the mobile app while the redesigned UI and control layout makes it easier to operate Part of that is a new physical gimbal mode switch that lets you select pan follow pan and tilt follow and FPV modes instantly nbsp Finally a new battery grip provides up to hours of battery life and can be easily changed out via a quick release system It supports PD fast charging at watts and can be charged independently or during use for non stop operation The DJI RS gimbal is now available from authorized retailers and at DJI s store priced at for the standalone gimbal and for the DJI RS Combo that adds a briefcase handle focus motor second control cable and a carrying case nbsp DJINext up is the RS Pro another technological tour de force from DJI It s built from carbon fiber so it weighs just pounds but can handle up to pounds of payload ーenough for pro cinema cameras like the Sony FX Canon C and RED Komodo Like the RS it also has the new automated axis lock system Bluetooth shutter button inch OLED touchscreen and gimbal mode switch nbsp The RS Pro borrows a key feature from the Ronin D the optional DJI LiDAR Range Finder It projects ranging points within a foot indoor area and powers a next generation focus motor with extra torque and one step mounting That allows for autofocus on manual lenses with no need for repetitive calibration according to DJI nbsp DJIThe LiDAR Range Finder has the same chip as the one on the Ronin D and a built in mm camera giving similar ActiveTrack Pro focus and gimbal tracking capabilities That will allow pro cameras to maintain steady clear shots in even more dynamic scenarios DJI says The RS Pro is now available starting at or in a combo with an extended quick release plate phone holder focus motor and kit Ronin Image Transmitter and more The LiDAR Range Finder will be sold separately priced at nbsp DJI has also announced that it s selling the DJI Transmission remote control monitor seen with the Ronin D as a separate device It uses DJI s O tech used on drones like the Mavic transmitting video in p fps at a ground range of up to feet with end to end ultra low latency Monitoring is done via the inch nit High Bright Remote Monitor nbsp DJIWith compatible devices like the RS Pro you can not only monitor and record video output but also control the gimbal camera recording and more using the DJI Master Wheel and Force Pro It also adds a DFS band that allows for up to channels letting large crews work simultaneously with ten or more transmitters The DJI Transmission arrives this September for or you can purchase the High Bright Monitor separately for nbsp Finally DJI announced that it s now a member of the L Mount Alliance and has partnered with Leica on the Zenmuse X L Mount unit that s compatible with Leica Panasonic and Sigma L Mount lenses And for any Ronin D buyers disappointed with the removal of Apple ProRes RAW support DJI announced that it will support Apple ProRes XQ the highest quality ProRes codec short of ProRes RAW nbsp	2022-06-15
