摘要：
This paper presents an improved algorithm for fog-degraded image clearness, which is designed to improve the visibility of outdoor surveillance system in fog weather. Image enhancement algorithm was considered and a moving mask-based partially sub-block overlapped histogram equalization algorithm was used to realize fog-degraded images clearness in every local region. The proposed algorithm can overcome the time-consuming drawback. Experimental results show that the improved algorithm can efficiently enhance the contrast of fog-degraded images and obtain satisfactory visual effects.
