Paper Abstract

This paper presents a new stereo matching method. The stereo disparity is estimated using a symmetric phase-only matched filter applied to foveal views of binocular stereo images. The foveal view at an image point is a simulation of the human retina image with a non-uniform spatial resolution, where the spatial resolution is the highest at the foveal center and decreases monotonically towards the periphery. Since spectral phase preserves the location of the image structure while it ignores spatial intensity correlation, the symmetric phase-only matched filtering applied to nearly identical images yields a very sharp correlation peak, which makes the detection of the image shift reliable and easy. Determining stereo disparity using the foveal view symmetric phase-only matched filtering is quite robust and accurate. The good performance of our stereo matching algorithm has been demonstrated for determining the disparity of remote sensing stereo images.
