摘　　要：图像去噪是图像处理中的重要组成部分.目前,针对点目标检测,人们已经发展了一系列比较成熟的滤波预处理算法.本文通过对红外点目标图像预处理方法的研究,给出了两种基于差分的背景抑制算法.最后针对仿真结果,对这两种背景抑制方法的去噪性能进行了分析比较.The technique of image denoising is one essential part of image processing. Now, a series of relatively mature filter preprocessing techniques have been used in point target detection. In this paper, the preprocessing methods for infrared point target images are analyzed and then two algorithms for background suppression based on difference are given. Finally, these two methods for background suppression are analyzed and compared with each other according to the simulation result.
