Document Summary
We have processes that combine our features into objects, this is one of the tasks that defines middle or midlevel vision opposed to low level vision. Middle (midlevel) vision: a loosely defined stage of visually processing that comes after basic features have been extracted from the image (early vision) and before object recognition and scene understanding (high-level vision) Middle vision: the goal of middle vision is to organize elements of visual scene into groups that we can then recognize as objects. Finding edges: lack of edge does not bother our visual system. I llusory contours: a contour that is perceived, even though nothing changes from one side of the contour to the other in the image. The tendency of the visual system to go beyond the info given was problematic for one of the earliest group of perceptual psychologists, the structuralists.
