I think it's both C and NN. Don't forget each new C layer groups information from previous layers; using just a single C layer won't do you much good. It might not reflect brain much but it kinda resembles what retina/visual cortex neurons do; CNNs were actually inspired by visual field maps found in visual cortex and somebody had the idea that C is the most similar CV operation we have, and put them together. To everyone's surprise it worked nicely.

- bitL 9y agoIt's probably just very rough "resemblance" :D It is said CNNs were "inspired" by visual field maps; I am 100% sure we know very little about how that part of brain works and maybe somebody just took a look at main/thickest connections between neurons there and tried to assemble them in a NN to see if it helps.
- scotty79 9y agoI'm thinking exactly same thing.
