小目标红外图像背景噪声的抑制及方法讨论
Background Noise Suppression in Small Targets Infrared Images and Its Method Discussion
摘要
提取复杂背景条件下目标红外信号的方法有很多,而采用背景噪声抑制的方法是检测目标红外信号的一种有效方法.介绍了抑制小目标红外图像背景噪声的三种方法:空域高通滤波法、频域高通滤波法和自适应门限背景抑制法,并对各种方法的抑制结果进行了验证与分析.
Abstract
There are various methods to extract the signals of targets in a sequence of infrared images against cloudy background. Background noise suppression is an effective method for extracting the signals of targets in infrared images. Three methods including EHPF, BHPF and LHPF for suppressing the background noise in small targets infrared images are described. The results of background noise suppression by using these methods are verified and analyzed.
