Abstract: This paper presents a new blind pixels approximation algorithm based on the scene moving analysis for the infrared focal plane array(IRFPA). It is known that there exists strong relativity between neighboring images in image sequences. By moving scence analysis, moving parameters can be calculated from image sequences. Then the pixels in the previous frame image can be found which correspond to blind pixels in the current frame image. And these pixels are used to approximate blind pixels in the current frame. This algorithm can make objects in the aproximated image maintain its edge completely. Theoretical analysis and experimental results show its effectiveness.

Key words: infrared focal plane array, blind pixels compensation, moving analysis, maintain edge
