Non-Local Single Image DE-Raining Without Decomposition

Abstract

It is challenging to remove rain steaks from a single rainy image because the rain steaks are spatially varying in the rainy image. On top of a new insight in single image de-raining, a nonlocal de-raining algorithm is proposed in this paper to remove the rain streaks from the rainy image. The rainy image is not decomposed into different layers by the proposed algorithm. Experimental results validate the proposed algorithm.
