Document Type and Number:
WIPO Patent Application WO/2022/022260
Kind Code:
A1
Abstract:
An image style transfer method and an apparatus therefor, relating to the technical field of image processing. The method comprises: obtaining an original picture and initial drawing parameters (S101); taking a plurality of pixel points in the original picture as a plurality of sampling points, and obtaining colors respectively corresponding to the plurality of sampling points (S102); obtaining a plurality of mapping points respectively corresponding to the plurality of sampling points on a virtual drawing canvas (S103); generating virtual drawing brushes according to the initial drawing parameters and the colors respectively corresponding to the plurality of sampling points (S104); and on the basis of the plurality of mapping points, using the virtual drawing brushes for drawing on the virtual drawing canvas to generate a target picture after style transfer, the drawing process comprising a plurality of drawing stages, drawing being performed on the virtual drawing canvas by using the corresponding virtual drawing brush in each drawing stage, the drawing being performed on a picture drawn in the previous drawing stage in each drawing stage, and the virtual drawing brush in each drawing stage changing according to a preset change mode (S105). According to the method, a manner that a use draws a painting is realistically simulated by means of multi-layer simulation; on a blank virtual drawing canvas, multi-layer drawing is performed on the basis of an original picture to obtain a target picture after style transfer, thereby obtaining a nearly real painting effect, improving the reduction degree of the original picture, and enhancing the image style transfer effect.
