Hypothesis based problem solving with bash and Imagemagick

Показать описание
This is NOT a computer vision tutorial. In this video, we walk through problem-solving using programming. As a test case, we extract color features from GIF frames to detect strobe effects. We use Imagemagick's identify tool to look for interesting patterns that we can use to make the GIF strobe detector.
This video is a bit longer because we walk through the entire problem, from identification to testing, to software creation. We write the POC logic in a bash script in Linux.
Give your hypothesis about GIF detection features in the comments below!
Download the script and test data from the link below. Try to detect features from the other to GIFs and send a pull request on Github.
