摘　　要：基于传统的图像复原算法——逆滤波,提出了改进的MTFC遥感图像复原算法。通过对比分析图像不同频点的补偿函数曲线以及不同补偿因子的复原效果,优化了MTFC算法,在提高图像质量的同时较好地抑制了噪声。同时,采用不同的卫星遥感图像验证了算法的适用性,体现了其应用价值。This paper proposes an improved MTF restoration algorithm for remote sensing image based on inverse filtering,a traditional image restoration method.The improved algorithm is accomplished by optimizing the compensating curve shape at different frequency and the compensating factor.The quality of resultant image is better than before and the quantitative results are satisfying.Moreover,the optimal algorithm is adaptive to various remote sensing images and it overcomes the limited adaptability of former work.
