The research of foggy blurring image restoration

In this paper the restoring technique of foggy gray blurring image and foggy color blurring image are mainly studied. Global histogram equalization method and local histogram equalization method are all used to restore foggy blurring gray image, hue saturation adjustment method and Retinex method are all used for restoring foggy blurring color image. The experimental results show that the optimal restoring algorithm is different for different image because of the difference in light, fog seriousness degree, ratio between bright and dark areas, and noise. Therefore, it is needed to select right algorithm to restore foggy blurring image with different degradation reason.
