Abstract
As an important remote sensing image pre-processing method, radiation correction is essential to reduce deviation introduced by environment factors, especially for tasks such as image compression, image fusion, and object recognition. In this paper, we propose a new radiation correction method for remote sensing images based on change detection. Due to the fact that areas of with significant changes deteriorate performance of radiation correction, these sections should be detected and discarded in the image firstly. Then general radiation correction technology is considered to have better performance on the rest sections. The core idea of the proposed method exists in the combination of radiation correction and change detection. Experimental results prove validness of the proposed method. As an application example, this method used in image compression shows better performance than other compression technologies.
