Abstract Details

A new computational analysis is described that is designed to estimate the shape of an observed surface from the optical projections of its contours in a 2D image. This model assumes that contours on a surface are generated by a series of parallel planar cuts, and it estimates the relative depth between any two surface points based on the number of contour planes by which they are separated, and the apparent 3D orientations of those planes. A psychophysical experiment was performed in an effort to compare the model predictions with the perceptual judgments of human observers about the 3D relief of depicted surfaces. Stimuli consisted of sinusoidally corrugated surfaces with contours that were oriented in different directions. The results reveal that observers’ perceptions vary systematically as a function of contour orientation, and that similar distortions can also be generated by the model with appropriate parameter settings.
