You can master Computer Vision, Deep Learning, and OpenCV - PyImageSearch
Image ProcessingImage processing is the cornerstone in which all of Computer Vision is built. Follow my image processing guides to learn the fundamentals of Computer Vision using the OpenCV library.
Today’s blog post is part of a two part series on working with video files using OpenCV and Python. The first part of this series will focus on a question emailed in by PyImageSearch reader, Alex. Alex asks: I need…
