Reading this reminds me of my first work at a big lab in the field of cognitive sciences. Basic we were tracing the source of visual awareness which is a part of consciousness. The goal is to find identify the tiniest bit leads to awareness of visual perception of objects, is it bottom-up like pixels to shapes to boom! It's a circle! or it's a ring! Or is it top down, I feel that there's a hole, and then figure out what that about. The academic debates are like 30 some years long about this, but pixels take the leads because it is easier to implement with math, you can get a computer to "understand" moderately complex shapes, or identify the owners of many many faces. Anyway it ties at the understanding of topology of images, could a computer understand a shape however its properties changes? In motion pictures, is a movement considered to be an appearance of new object with "destruction" of old one, or just a move. How do you define that in the language of mathematics that both covers machine and human vision. It was some joyful years of working with the scientists but I was too under-educated to even remember how have they put computability and topology in the same work.
