Paper Abstract

The color composite DMC images are obtained by calibrating, mosaicking and color composite fusion processing, but the quality usually is still not good enough to be satisfied. That mainly appears that, between the four images in the color composite DMC image, in a narrow range, there is a smooth transition, but for the overall image, the radiometric differences still exist. This paper, based on analyzing the character of the residual radiometric differences in color composite DMC images, proposes a post-processing approach to improve the images' quality and achieve high quality imagery. The procedure employs a multi-scale adjustment scheme to ensure a more satisfied result and each adjustment scheme is performed in a different spatial scale. Finally, experiments are given and results show that the approach proposed by this paper can remove the residual radiometric differences and acquires images with higher quality.
