Basic building blocks of visual perception, without them we lose our ability to see. Shapes are separated from other shapes or background by contours. Regions of relatively uniform brightness in the visual system. Most basic level, the visual system seems to divide the visual field into relatively uniform brightness. Region in the retinal image where the light intensity (wave length composition) changes abruptly. Depend on luminance, color differences, or wave-length characteristics.
