Chinese traditional painting style migration method and system based on Laplacian pyramid

The invention discloses a Chinese traditional painting style migration method and system based on a Laplacian pyramid, and relates to the technical field of computer vision, and the method comprises the steps: constructing a multi-scale style migration model based on the Laplacian pyramid; the multi-scale style migration model comprises a Laplacian pyramid decomposition module, a basic style migration network, a detail enhancement network, an edge information selection module and a Laplacian pyramid reconstruction module; inputting the preprocessed content image data set and the preprocessed style image data set into a multi-scale style migration model for training, and optimizing the multi-scale style migration model by using a style loss function and a content loss function to obtain a multi-scale style migration generation model; and inputting the target content image into a multi-scale style migration generation model to generate a stylized image of the Chinese traditional painting style.
