My CS teacher in high school had a lesson with us about horseshoe crab's eye, which apparently does not see anything that is larger than the field of view of the eye, allowing it to consume smaller organisms and omitting larger organisms. We used a neural network model in excel for such purposes.
He was (and hope he still is!) a great person, who taught me being curious and insightful in the computer science field. Taught me about Donald Knuth, TeX and many more things.
- pinoy420 2y agoDoes not see anything that os larger than the field of view? I can’t conceptualise this. How? Surely this is the same as humans where if you had a big enough uniformly lit object in front of you, you couldn’t “see” it?
- davedx 2y agoImagine if you only see things if you can see their edges. (most eyes do edge detection in the retina before signals hit the visual cortex)
- p0w3n3d 2y agoat least the model we used was behaving like this. It was making objects larger than it visible as a line and smaller visible as a whole (like coloring fill in MS Paint). Objects that fit in the eye were colored and larger were not. However this was a neural network model (shown in excel as a matrix) - I wonder where did he get it from. When I wrote the above, I tried to find it but couldn't
