Without discussing the implementation of these files, let’s run the project to ensure everything is working correctly. There’s also an XML layout file named activity_main.xml, as illustrated in the next figure. java extension, but it isn’t just displayed in the Android project view.

It includes interfaces with Python, Java, and MATLAB. It is a free, open source library originally written in C++. OpenCV is a vision library built for doing complex, real-time operations on images.
