Abstract

The color composite Digital Mapping Camera (DMC) images are obtained by calibrating, mosaic and color composite fusion processing through the post-processing software, but sometimes the color transition in the transition area is not smooth enough and there are still residual radiometric differences. This paper, based on analyzing the characters and causes, proposes a self-adapting repair approach to remove such phenomenon. The approach first gives a strict proof about the feasibility to locate the exact position of seam-line and transition area, and adopts the principle of edge detection operators to detect the exact position automatically. Then it employs a multi-scale adjustment scheme which is mainly carried out by two different spatial scales and includes the "break" processing and "seam" removal. Experiments indicate that the approach can repair the color composite DMC images with residual radiometric differences effectively.
