I was recently at the ACM Symposium on Applied Perception, where I saw a keynote on visual attention. The speaker (Laurent Itti) showed an animation that blew my mind. It showed a video of fish swimming in the ocean, and next to it, the same video as "seen" by the retina. The latter was upside down and distorted beyond recognition except at the fovea, which darted around to salient locations in the video. I had heard it explained before that "your eye doesn't 'see' images, your brain reconstructs them," but I had never before seen it illustrated so well.
I want to find a similar animation to show friends and students, but I'm having trouble finding anything. Searches yield mostly diagrams of light passing through the eye or something similar. The only thing I've found that shows what an image actually looks like when it reaches the retina is this picture.
It's a nice start, but I'd really like an animation, like a video or GIF, to show how the brain stitches together the retinal images at each fixation into what seems like a coherent image/video.
Can you help me find such an animation? Something that shows what a raw visual feed actually looks like?
