Paper Abstract

This paper presents a binocular disparity computation method by using Gabor wavelet pyramid to recover depth structure of the scene. In our previous work, differential Gabor filters were used to extract image flow from two image frames. With Newton-Raphson method, the differential Gabor approach can be extended to compute binocular disparity and, hence, to recover the depth structure of the scene. To illustrate the effectiveness of the Gabor wavelet pyramid for recovering depth structure, we synthesized a pair of stereo random-dot images with three centered pyramidal planes. Experimental result shows that the performance of the Gabor wavelet pyramid approach for depth recovery is good and the convergence rate is very fast. An architecture of the differential Gabor wavelet pyramid for binocular disparity computation is proposed. The computational structure of the pyramid is very simple and it is easy to implement with parallel processor.
