Computer Vision Using Go And OpenCV 3
summary
GoCV exposes OpenCV 3 to Go via cgo wrappers so idiomatic Go code opens cameras, creates Mats, and runs classifiers. It blurs faces with a Haar cascade and finds motion with a MOG2 background subtractor, serves MJPEG streams from a webcam in pure Go, and loads TensorFlow models into OpenCV to classify objects on a Tello with TensorFlow via OpenCV. Demos compile-and-run but the drone demo needs ffmpeg rewrapping of H264 and occasional rebooting.
