Image rain imprint removal method and system and storage medium

The invention provides an image rain imprint removal method and system and a storage medium, and relates to the technical field of image processing.The method comprises the steps that firstly, images with rain imprint and images without rain imprint are obtained, a data image set is formed, the data set is input into a constructed RCR-Net rain removal model to be trained, shallow layer features of rain imprint are extracted through an encoder and transmitted to a decoder, and the image with the rain imprint and images without the rain imprint are obtained; the method comprises the following steps of: extracting deep rain imprint features by utilizing a decoder, then utilizing a Refine network to obtain a rain removal picture, finally processing a rain image to be predicted by utilizing a trained RCR-Net rain removal model, outputting a rain removal prediction picture, fully extracting shallow feature components of rain imprint and high-dimensional feature components under different scales in a rain removal pr
