>Yet Lines-As-Edge supposes that the vision system discards all of this other information present in an image, for just this one special case. Why? The "other information" is not discarded, it's just not processed yet I think this is a misrepresentation of how the visual system works and views the vision system as more "batch" than the continuous process it is. So if you think about it as a time series problem, when light hits the retina then "inference and processing" starts with a kind of "fast and rough" inference and then proceeds to fill in details and contextual coherency follows I'd have to go pull out the textbooks but if you look at visual interpretation sequence it's something like: Movement > edges > color > details So your visual system acting as an object detector - from sensor to inference - makes inferences about movement first, then infers the edges, then infers color and finally additional details in the last few ms Nothing is "discarded" it's just less relevant in the first pass and additional refinements happen mostly sequentially - this all happens in nearly imperceptible time.
