Receptive Field Position Disparity Estimation Using Cross-Correlation Algorithms

Abstract—In human vision, retinal disparity is an important attribute which is the main reason for stereopsis. Mechanisms used for encoding binocular disparity through simple cells in striate cortex are difference in receptive field position and difference in receptive field phase. In the case of two dimensional objects position disparity has the major contribution in binocular fusion. Since human brains are more similar to correlators, cross correlation algorithms are the most simplest and natural method for disparity estimation. This paper is a comparative study of different cross correlation measures that can be used for the estimation of receptive field position disparity
