You can master Computer Vision, Deep Learning, and OpenCV - PyImageSearch
Last updated on July 7, 2021. A couple weeks ago we learned how to classify images using deep learning and OpenCV 3.3’s deep neural network (dnn ) module. While this original blog post demonstrated how we can categorize an image…
