You can master Computer Vision, Deep Learning, and OpenCV - PyImageSearch
I’ve received a number of emails from PyImageSearch readers who are interested in performing deep learning in their Raspberry Pi. Most of the questions go something like this: Hey Adrian, thanks for all the tutorials on deep learning. You’ve really…
