Abstract

Distortions between decompressed image and original remote sensing image can be divided into two parts, geometric degradation and radiometric degradation. The geometric degradation is the error or difference of pixel's position or geometric structure compared with these in original one. Measuring this geometric distortion is very important in some area, such as digital photogrammetry and computer vision, because it is this distortion that influences the position of object. This paper provides a modified method for measuring this distortion on the basis of modified least square (MLS) image match.
