DETECTION AND ANALYSIS OF WEAK TARGET WITH INFRARED IMAGE BASED ON K-L TRANSFORM
基于K—L变换的红外图像弱小目标检测与分析

In view of the characteristics of the low contrast and small dimension of targets and the complexity of background in infrared image, a method of detecting and describing infrared weak target was presented with improved K L transform and generalized K L transform. Thus the infrared weak target can be detected in low signal to noise ratio.
