To solve the visibility of outdoor surveillance system in foggy weather,a weather degraded image sharpening algorithm is proposed.Combined the Approximate Point Spread Function Examining(APSFE) algorithm and Partially Overlapped Sub-block Histogram Equalization(POSHE) to wipe out the weather factor which influences the quality of image.Taking sub-block and step size input image size,and can use the preset value which needn't parameter estimation,thus realize the improved algorithm.Experimental results show that,the improved algorithm has good adaptivity and instantaneity.
