The original implementation of GOTURN is in Caffe, but it has been ported to the OpenCV Tracking API and we will use this API to demonstrate GOTURN in C++ and Python. The idea here is to get the computer to track the green ball and then send the correct spatial coordinates to the robot arm which would then follow the ball in space. In other words, all of the actual computations are performed at a native level. It works best on binary images, so we should first apply thresholding techniques, Sobel edges, etc. Hand gesture recognition is exceptionally critical for human-PC cooperation. jp - OpenCV: 物体追跡(Object Tracking)サンプルコード -.
