| 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. |
