Abstract
En 中文
Single image rain removal requires a large number of channel features and image texture in the process of rain removal. In this work, we propose a Channel Memory Network (CMN) for single-image rain removal, which is a multi-stage rain removing network structure similar to recurrent neural network. One Channel Memory Block (CMB) is also employed by CMN to extract rain streaks texture feature efficiently. CMB is able to focus on features on the channel and optionally selects useful information. In addition, Channel Attention Block (CAB) is adopted in skip connection to enhance the features from previous modules. Gated Recurrent Unit (GRU) reduces the loss in the process of parameters sharing and selectively transfers the feature to the next stage. The network structure shares a lot of parameters so that more rain streaks information can be used efficiently in the process of feature transmission. A quantity of experiments show that the performance of the proposed method is better than that of the state-of-the-art methods on five synthetic datasets.
