I wanted to extract diagrams from youtube lectures. Had no idea how to go about it.
i said:
"i don't know what it is, but if you think about frames in a video, and the screen shows the speaker vs showing a diagram - something is different because the diagram is static, has less movement and less colors. What is it?"
"ahh. I see what you are talking about is entropy. There is more randomness in a frame with movement or a person than a frame with a diagram. here is a function that plots the frame entropy over time for a video..."
and then i wen't back and forth with it to build a whole workflow and make the analysis tool be interactive. So even though it was just a text conversation, by writing the visual features i wanted, it was able to implement it for me. Pretty wild.
