Abstract: A simple depth-cueing method to restore a degraded weather image is suggested, based on the dichromatic atmospheric scattering model developed as shown. It can be used to eliminate the effect of bad weather on an image with few extra information provided by user and without any information needed on depth and weather. For the weakened intensity of image due to the elimination, the histogram method is used to adjust so as to enhance the intensity of the image. The results of a simulation done on MATLAB platform show that the method suggested is quite good at restoring degraded weather images.
