Fast Removal of Rain Streaks From a Single Image via a Shape Prior

Recently, single-image rain removal has attracted sustained attention. In this paper, we utilize a simple shape prior, the fact that the rain streaks often appear in an elongated elliptical shape, in a particular way for single image de-raining. With this prior, the patches of the rain layer are forced to have a high correlation with our synthetic ellipse matrix. Then, the rain layer is refined during each layer decomposition process with the...
