Chinese character image inpainting method based on strokes

Abstract

A Chinese character image inpainting method based on strokes belongs to the fields of computer virtual reality technology and machine vision. Information used for inpainting a Chinese character is limited in an image or a plurality of images with the same source as the image. Before inpainting the Chinese character, a damaged Chinese character in the image are broken up into strokes. A template assembly containing the Chinese character and the strokes of the Chinese character is built. During inpainting of the Chinese character, an undamaged portion of the damaged Chinese character or outlines of the strokes are extracted, a corresponding outline section of a remained outlines in the stroke assembly is found, a corresponding possible stroke is determined through the corresponding outline section, then a possible stroke most similar to an original stroke is selected from possible similar strokes, and finally a Chinese character damaged portion is restored according to the corresponding template, and a corresponding image portion is inpainted. Compared with other image inpainting methods, the method can store structure information of the damaged portion of the Chinese character well.

Description

technical field [0001] The invention belongs to the field of virtual reality technology and computer vision, and in particular relates to image restoration and stroke extraction of Chinese characters. Background technique [0002] Image restoration technology is an important branch of image restoration technology, which is applied to the protection and damage restoration of ancient books, ancient paintings and other cultural relics, and is a technology to modify damaged images. There are two main development directions of image restoration technology. One is to start from the meaning of image repair itself, that is, to repair small spots and scratches on the image, but not to repair large areas of texture. Most image inpainting models in this direction are based on partial differential equations or variational problems. The inpainting model based on the variational problem has a good theoretical basis, but the inpainted image is unnatural, and the outline of the selected t...

Problems solved by technology

[0004] The technology of the present invention solves the problem: overcomes the disadvantage that the existing image technology cannot effectively restore the structural information of the damaged part of the image, and provides a Chinese character image repair method based on strokes, which solves the problem that the image repair is difficult to restore the structural information of the damaged area, and can effectively restore Chinese characters.
