To resolve the fog-degraded image problem,fog removal method based on bilinear interpolation dynamic histogram equalization(BIDHE) was proposed.The original image was split into some sub-images with same size,and the histogram of each sub-image was partitioned by the local minima.The gray level range in output image could be calculated according to the equations,and then HE was applied to each sub-histogram,and the defogged image was achieved by the bilinear interpolation.A real fog degraded image was selec...
