Contrast Enhancement Method for Fog-Degraded Image Based on Fuzzy Logic
JI Yu-bo · 2011
To improve the visibility of fog-degraded images,a method for fog-degraded image clearness based on fuzzy logic was presented.The degraded image was mapped from the gray area to the fuzzy area,and then the fuzzy entropy was calculated to obtain the change rate of a pixel.By choosing the appropriate threshold for the fuzzy entropy,the image pixels were put into two categories,and then achieve different fuzzy feature enhancement operations.Experiment results show that this method can efficiently improve the degradation of image and enhance the clearness of image.
