Abstract: A single image deraining method is proposed.

A weighted blending step blends a (n?1)-th stage low-frequency derain image with the n-th stage derain image to generate a (n?1)-th stage blended derain image. A second inverse wavelet transforming step recombines the (n?1)-th stage high-frequency derain images with the (n?1)-th stage blended derain image to form a (n?1)-th stage derain image, and sets n to n?1 and repeats the last two steps.
