JavaScript is not sufficient for very heavy calculations. Doing it in plain JavaScript would be highly ineffective. In this tutorial, we will be building an example project which uses the device’s camera to take a photo, processes it with native code and returns the information if the taken image is blurred or clear. (Newbie) React Native with OpenCV : reactnative – Reddit Answers are that it’s possible but with no example of how to do it.opencv/opencv – GitHub A problem with linking libraries with no indication on how to do it in the first place.wix/react-native … An unanswered question about React Native and OpenCV.Yet there are no React Native bindings.” Also it’s incomplete and uploading 500+MB of the OpenCV library is not a good idea. GitHub – ma-pe/react-native-opencv: OpenCV Bindings for React … “Currently being developed.If we google for “react native opencv” we stumble upon the following links: It uses the same design as React, letting you compose a rich mobile UI from declarative components. React Native lets you build mobile apps using only JavaScript. React Native was first released in 2015 by Facebook. Full integration is available since version 2.4.2 (2012). In 2012 OpenCV development team actively worked on adding extended support for iOS. Since 2010 OpenCV was ported to the Android environment, it allows using the full power of the library in mobile applications development. The library is used extensively in companies, research groups and by governmental bodies. OpenCV has more than 47k people community and an estimated number of downloads exceeding 14 million. It can also find similar images from an image database, remove red eyes from images taken using flash, follow eye movements, recognize scenery and establish markers to overlay it with augmented reality, etc. These algorithms can be used to detect and recognize faces, identify objects, classify human actions in videos, track camera movements, track moving objects, extract 3D models of objects, produce 3D point clouds from stereo cameras, stitch images together to produce a high resolution image of an entire scene. The library has more than 2500 optimized algorithms, including a comprehensive set of both classic and state-of-the-art computer vision and machine learning algorithms. OpenCV was built to provide a common infrastructure for computer vision applications and to accelerate the use of machine perception in the commercial products. OpenCV (Open Source Computer Vision Library) is an open source computer vision and machine learning software library. Let me show you how I used the OpenCV and React Native step by step to process my images, but first a few words of introduction. The size of your mobile app will be only a dozen or so megabytes bigger.Lots of tutorials all over the Internet and solid official documentation of OpenCV.OpenCV enables React Native developers to process images on mobile devices (most likely you’d like to process images taken by your device’s camera).
