Abstract

A hybrid approach that uses edge information is proposed. At the first step, edge pixels are matched using adaptive windows that vary their shapes according to the direction of edge. At the next step, pixels outside edges are matched using adaptive windows that are limited by edge contours. The authors also constructed a pyramid structure using a wavelet transform. The disparity information obtained by matching low resolution images is utilized for interpolating the disparities of high resolution pixels unmatched
