Abstract

In the field of computer vision, rain streaks or raindrops may make the images taken on rainy days blurred, and reduce the quality of the image. Aiming at the problem of low image quality in rainy days, this paper proposed a novel image rain removal algorithm based on channel attention and gated recurrent unit to remove rain streaks. The basic idea is as follows: first of all, it extracted features from the training image through the residual memory block. Then, it increased receptive field with the extracted features through the feature enhancement module, identified and enhanced rain streaks features of different levels, which were passed to the subsequent recurrent network. Finally, during the recurrent network, the gated recurrent unit block achieved parameter sharing between different recurrent stages. The experimental results verify the effectiveness of the algorithm on complex datasets by using objective evaluation indexes and subjective visual effects.
