Speckle reduction of infrared image and its hardware realization

Regarding to big black speckle and cell like stripes in the IR images of a IR observation system introduced by the assembly precision, environment, the nonuniformity correction method and etc. after correction of the images for nonuniformity, an adaptive algorithm of nonuniformity correction based on neural network is introduced in this paper. And a real-time video signal processing system based on DSP and programmable devices is described in this paper in detail. Experimented with the IR observation system, the algorithm is able to despeckle images adaptively and the real-time realized in the hardware system proposed in this paper.
