Inscription restoration method based on contour feature description of Chinese character image

Abstract

The invention provides an inscription restoration method based on the contour feature description of a Chinese character image. The method is applied in the fields of computer virtual reality technology, machine vision, image processing and inscription restoration, wherein the information is limited in a homologous inscription or the calligraphy works of a single writer. During the pre-treatment process, after the inscription is divided into single Chinese characters, the component decomposition and the stroke decomposition are conducted on each extracted single Chinese character. The acquired components and the acquired strokes of Chinese characters together form a component-stroke template set. During the restoration process of damaged Chinese characters, firstly, the structural information and the contour information of the credible component/stroke part of the damaged Chinese characters are extracted. Based on the partial correspondence relationship of the structure matching and contour segments, a template that is highest in similarity is found out of the component-stroke template set to be adopted as a signal source for restoring the damaged part of the damaged Chinese characters. Compared with other image restoration methods, the structural information and the contour detail information of the damaged part of Chinese characters can be restored on the premise that the original style of the inscription is well maintained.

Description

technical field [0001] The invention belongs to the fields of virtual reality technology, computer vision and computer graphics, and specifically relates to a method for decomposing strokes of Chinese character components for image restoration of inscriptions. Background technique [0002] Digital inscription restoration is a branch of image restoration. At present, in image restoration, predecessors have done a lot of work. In the field of image restoration, there are two main directions according to the meaning and method of image restoration. One is to start from the meaning of image repair itself, that is, the repair of small noises and irregular scratches on the image. This situation is generally solved based on partial differential equations or variational methods. The inpainting method based on the variational problem has a relatively sufficient theoretical basis, but the disadvantage of this method is that the inpainted image is unnatural and the outline of the inp...

Problems solved by technology

[0004] The purpose of the present invention is to overcome the above-mentioned shortcomings, solve the shortcomings that the existing image processing technology cannot effectively restore the damaged part of the inscription image, and provide a method for inscription restoration based on the outline feature description of the Chinese character image, which solves the problem that it is difficult to restore the structure of the damaged area of ​​the inscription image And the shortcomings of outline detail information, better solve the problem of inscription image irregularity defect
