On A Possible Mechanism Of Binocular Fusion

Described is a possible mechanism of binocular fusion In visual system based on continlous estimation of resulting "cor-tical image" doubling degree during ver-genoe eye movements. The mechanism does not require any search of corresponding sites in pair retinal images. The result of computer simulation of this mechanism are given. A sequence of information processing stages in binocular vision preceding recognition is discussed. Introduction It is assumed that corresponding sites of pair retinal images have to be found in order to provide the binocular fusion (I). This procedure seems to be rather complicated for real visual scenes (2). On the other hand some results of the biological experiments show that binocular fusion and stereopsis are possible when corresponding details of pair images have dissimilar shape (1,3.4,5). This suggest that the human binocular fusion mechanism is not based on corresponding sites search. In this paper a possible binocular fusion mechanism using a continious estimation of doubling degree of image (which is formed in visual cortex by superposi-tion of retinal projections) in the course of vergence is described. Some information processing stages in oinocular vision preceding object recognition Data available allow to distinguish the following stages of complex spatial scene analysis (i.e. when a number of objects overlapping in the visual field are situated in front, middle and rear plan).
