红外点目标图像的两种滤波技术

通过对点目标图像预处理方法的研究，采用基于形态学滤波与维纳差分滤波背景抑制算法，在matlab中利用这2种算法进行红外点目标图像的处理仿真。仿真结果表明形态学滤波有更好的滤波效果，实时性好，易于硬件实现，更适合作为红外图像弱小目标检测的预处理手段。

Preprocessing Based on Morphologic Filtering and Wiener Filtering in Point Target Image

The preprocessing methods for infrared point target image are analyzed, and then two algorithms of Background Suppression based.on morphologic filtering and Wiener filtering are presented. An infrared target image is disposed by matlab with these two algorithms. Finally, these two methods of background suppression are compared according to the simulation results. It＇s indicated that morphologie filtering is better than Wiener filtering, for the former has good filtering result, good real-time performance, and is easy to be implemented.
