摘要
Space-based optical images are mainly affected by space radiation, sky glow background and CCD noise interference, in which space radiation noise can seriously interfere with the subsequent target detection. In this paper, we propose a space radiation interference suppression algorithm based on multi-feature, and compare with three algorithms which are commonly used to eliminate radiation noise: a Laplacian edge detection algorithm, a fast algorithm based on histogram and a rank-ordered absolute difference (ROAD) algorithm. The experimental results show that the proposed algorithm can quickly and effectively eliminate space radiation noise.
