| Abstract: | 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. |
