Abstract

Based on an analysis of the visual mechanisms of perceiving stereoscopic images and video, algorithms are found for processing them, directed toward changing the relative position of objects over a range in the process of editing 3D scenes. It is shown that editing that consists of varying the screen parallaxes for all the objects of a scene must be accompanied by a corresponding variation of the scales of these objects and of their position relative to the line of the horizon in order to prevent conflict between such visual mechanisms as binocular vision, the mechanism for estimating the distance to remote objects by their angular size, the distance to the line of the horizon, and the accommodation of the eyes. This is achieved by separating the scene into range layers according to the number of objects. The results of the studies are confirmed experimentally and show that the process of editing stereoscopic images and video is fairly laborious and should be resorted to only in extreme cases.
