Delta Pulse Code Modulation Compression Relative to Stereo Image Matching.

Abstract

The effect of DPCM compression on stereo image matching is analyzed. It was determined for the aerial image used in the study that third order linear prediction is adequate and that DPCM compression does not introduce a bias in stereo matching. The standard error of mismatch for images compressed to one bit per pixel compared to 8-bit images is approximately two-thirds of a pixel spacing for each coordinate. (Author)
