Spatial vision pinhole plus lens focus light in retina - precondition of vision achieve neurally - more than percieving things in 3d - spatial vision. What does visual world look like? or designed for. Natural scenes that brain will extract and filter it our and individual neurons serve as filters. Diff. version of gratings what are the bound or limitations of acuity primary visual pathway - retina - synapses - cortex to area 17 functional prop. of stripe cortex. Natural scene statistics: why care about gratings? gutenberg"s invented printing press - impact on why it is impt. to represent something gratings in visual world is the building block e. g. fourier"s transform assoc. with natural world as well. Why care about sine wave gratings? create filters that specialize and detect 1 building block at a time e. g. only detect a or.
