[0070] Image Style Transfer (IST, Image Style Transfer) studies the style transfer between natural images. Its task is to transfer the style of the reference image to obtain a stylized image based on the content of the original image. figure 1 is a flow chart of an image style transfer method shown in this application, such as figure 1 As shown, the method is applied to electronic equip...

Abstract

The invention discloses an image style migration method and device, an electronic device and a storage medium. The image style migration method comprises the steps of obtaining a to-be-processed image; processing the to-be-processed image by adopting a style migration model to obtain a first stylized image; wherein the style migration model is obtained by carrying out model training in advance according to the content image, the second stylized image and the third stylized image, the second stylized image is obtained by carrying out stylization processing on the content image, and the third stylized image is obtained by processing the content image by adopting a neural network model. According to the method, the style migration model obtained through pre-training is adopted to perform style migration processing on the to-be-processed image, the processes of solving, optimizing and the like on the loss function in the process of executing style migration are avoided, and therefore rapidstyle migration is achieved. Moreover, the style migration model is obtained by supervising and training the neural network model by adopting paired input and output samples, so that the stylizationeffect of the model can be improved.

Description

technical field [0001] The present application relates to the field of computer technology, and in particular to an image style transfer method, device, electronic equipment and storage medium. Background technique [0002] In the field of image processing and computer graphics, image style transfer (IST, Image Style Transfer) is a very important and challenging topic. According to the different problem scenarios that are actually dealt with, IST is divided into sub-topics such as artistic style transfer, fidelity style transfer, and semantic style transfer. IST has a wide range of application scenarios, including image editing, image synthesis, image special effects, etc. [0003] The current method of researching IST generally uses convolutional neural network (CNN, Convolutional NeuralNetworks) to extract the features of the content (content) and style (style) graph and construct the Gram matrix to define the content loss and style loss, and then optimize the solution to...
