The invention provides an image reconstruction method and device based on an example. The method comprises the following steps of: dividing a first image to be converted into first image blocks with the size of r*r, wherein r belongs to an element in a preset set K; dividing a preset target style image into second image blocks with the size of r*r; obtaining the target second image block of each first image block; fusing the target second image blocks of all first image blocks, reconstructing the target style image of the first image, and taking the target style image of the first image as a converted second image; obtaining the second image corresponding to each element r in the preset set K in sequence; and adopting a multi-level fusion strategy to fuse all reconstructed second images to obtain the target style image of the first image used for output. By use of the method, the structure information and the texture information of the input image are used for realizing the target stylized reconstruction of the image so as to optimize the stylized reconstruction effect of the image.
Description
technical field [0001] The present invention relates to the technical field of image processing, in particular to an example-based image reconstruction method and device. Background technique [0002] With the development of science and technology, the equipment that people can use for image acquisition is becoming more and more diverse, and the demand for the expression form of the image itself is also becoming more and more diverse. Taking sketch image synthesis as an example, it will be difficult for people without professional drawing skills to draw a vivid sketch portrait. In recent years, in view of the application of portrait sketches in digital entertainment and judicial evidence collection, more and more people have begun to pay attention to the automatic generation of face sketches. With the help of automatic portrait sketch synthesis technology, non-professional users can easily complete a sketch portrait. In terms of judicial evidence collection, the artist usu...
