Document Summary

Spatial vision: ability to visually detect spatial patterns. Detecting patterns in multiple scale zoom in and out looking patterns within individual seashell or zoom out and see the whole picture. Abraham lincoln usually when you blur the image, it makes it difficult to recognize. We are highlighting patterns in a course scale. How do we measure the ability to perceive patterns at different scales) Relation to receptive fields size perception at different scales, and how that relates to rf size for various neurons (ganglion cells or simple and complex cells) Large rf pulling information from a larger area not able to detect tiny structures if you have large receptor fields. Direct correspondence with size of rf with the neurons detecting structure in the image. The visual system analyzes information through multiple channels (channel each channel is responsible for a particular spatial scale fine or coarse scale have different levels in between) You can take this image, and analyze the image.
