contour 

The outline of a part of a retinal image where the light intensity changes abruptly corresponding to the boundaries of objects in the visual field. The physiological basis of contour perception and edge detection is thought to be mediated by the responses of complex and hypercomplex cells in area V1 of the primary visual cortex.
Illusory contour's (subjective contours) are contours perceived in the absence of a lightness or colour difference as in the Kanizsa figure. They are thought to be processed in area V2 of the visual cortex. See visual association areas; parvocellular visual system.

contour (kon´tōōr),

n the external shape, form, or surface configuration of an object.
contour, anatomic height of
n a line encircling a tooth to designate its greatest convexity.
contour, buccal,
n the shape of the buccal aspect of a posterior tooth. It normally has occlusocervical convexity, with its greatest prominence at the gingival third of the clinical buccal surface.
contour, gingival,
n the shape of the natural or artificial gingiva as it approximates the natural or artificial tooth.
contour, height of,
n the greatest convexity of a tooth viewed from a predetermined position.
contour, proximal
n the form of the mesial or distal surface of a tooth.
contour, restoration,
n the restoration of a proper contour where surfaces of teeth have been destroyed by disease processes or excessive wear.
contour, tooth,
n a shape of a tooth that is essential to a healthy gingival unit because it enables the bolus of food to be deflected from gingival margins during mastication.
