Method used for extracting unearthed bamboo slip and silk character pattern image and based on digital image processing

Abstract

A method used for extracting an unearthed bamboo slip and silk character pattern image and based on digital image processing belongs to the technical field of computer image processing of unearthed bamboo slip and silk. The method is characterized in that Photo shop digital image processing software is used for extracting a digital image of the unearthed bamboo slip and silk, and steps of capturing of single character pattern, re-distribution of gray level between each character stroke ink mark and a bamboo slip and silk background according to original ratio, distinguishing of radical selecting area of a single character and a stroke selecting area in each radical by using an original basic stroke table and a basic radical table area, reserving of all stroke images in each radical selecting area and deleting of non-stroke ink mark image are conducted sequentially, and extracting of a single character pattern is achieved. By means of the method, basic radical separation is used as a basis, thorough separation of the unearthed bamboo slip and silk character patterns and a bamboo slip and silk background is achieved, character pattern images which reserve character original information and are clear and distinguishable are presented, and the technical problem of great distortion of images caused by copying the unearthed bamboo slip and silk through a traditional writing method at present is solved.

Description

technical field [0001] The present invention relates to a new method for analyzing and extracting font images of unearthed slips and silks by means of Photoshop digital image processing software, which belongs to the fields of unearthed literature research, ancient writing research and calligraphy research. The unearthed slips and silks mentioned here mainly refer to bamboo slips of the Warring States Period , wooden tablets and silk books. Background technique [0002] The bamboo slips and silk documents in the unearthed documents have been buried underground for a long time. Due to the relatively stable environment before unearthed, they can maintain a relatively primitive appearance. Most of them have been stored for thousands of years, and their value is self-evident. In recent decades, with the increase in the number of unearthed bamboo slips and silk, the collation and research work has also become increasingly sophisticated. Wang Guowei once said: "Most of the new le...

Problems solved by technology

[0006] The purpose of the present invention is to provide a new method for extracting unearthed bamboo slips and silk glyph images, which can take into account the advantages of traditional glyph processing methods, and use digital image processing technology to combine a single glyph with its background without losing the details of the glyph image. Thoroughly separate and objectively reproduce the glyph images of unearthed documents to solve the problems of lack of original details, calligraphy phenomena and distortion of glyphs in the unearthed texts processed by previous technologies
