You can master Computer Vision, Deep Learning, and OpenCV - PyImageSearch
Over the past few months I’ve gotten quite the number of requests landing in my inbox to build a bubble sheet/Scantron-like test reader using computer vision and image processing techniques. And while I’ve been having a lot of fun doing…
