摘要
红外图像预处理是红外小目标检测中的重要组成部分,其基本思想是通过背景估计实现对起伏背景的抑制,提高信噪比。对现今几种常用的背景估计技术进行了理论分析,指出了各自的优点与不足,并通过计算机仿真结果给出了直观的性能对比。对红外图像预处理的进一步研究具有指导意义。
IR image preprocessing is an important part of small targets detection, its basic thinking is to suppress the clutter of background through background estimation. This paper analyzes several background estimation technologies nowadays from theory. The correspond simulation results are given to compare their performances.
