Problems solved by technology

However, this idealized design faces difficulties in actual operation and consumes more funds.
It can be seen that although the traditional four types of methods have alleviated the problems caused by the Dongba cultural inheritance model to a certain extent, they are relatively extensive, slow and uneconomical in today's booming digitalization

Embodiment Construction

[0046] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0047] The invention provides a digital acquisition and image processing method for Dongba pictographs, which is an image processing method for handwritten Dongba pictographs for the inheritance and protection of Dongba culture, which includes the following steps:

[0048] 1) Digital image collection of Dongba classics and ancient books: CCD digital image acquisition system is used to collect images of scriptures, and the collected data is compressed to reduce the amount of data required to describe digital images.

[0049] Due to the age-old, fuzzy paper, and irregular fonts of Dongba classics, the collected images will have a certain amount of redundant data. Therefore, data compression is required to reduce the amount of data required to describe digital images. Among them, the specific image acquisition compression method is as follows:

Abstract

The invention relates to a method of digital acquisition and image processing for Dongba pictograph. The method includes the following steps: acquiring digital images of Dongba classic ancient books; denoising the acquired digital images; performing highlight treatment to the stroke characteristics of the digital images denoised and enhancing the contract ratio between the target characters and the background; performing contour detection to the characteristic highlighted digital image information; performing size unification to the contour detected digital image information to achieve the digital acquisition and image processing of the Dongba pictograph. With the application of the method of digital acquisition and image processing for Dongba pictograph, digital acquisition of fuzzy paper books is effectively achieved, the ratio of data volume compression is high, and clear images are obtained by smooth arc transition between the denoised noise and image signals. The method is convenient for digital inheriting and protecting and can be widely used in the field of characters and images processing.

Description

technical field [0001] The invention relates to a character image processing method, in particular to a digital acquisition and image processing method for Dongba pictographs in the field of computer image processing. Background technique [0002] The Naxi Dongba pictograph is considered by the international academic community to be the only pictograph still in use in the world today, and it is still used by the living Dongba priests to preside over various ceremonies, write letters, and keep accounts. Through a century of research, international Naxi scholars believe that Dongba script is a form of writing in the transition period from pictorial writing to pictographic writing. In addition, the Mayan script and oracle bone inscriptions in Central America are more primitive. There are as many as 30,000 volumes of Dongba classics written in Dongba pictographs, with a total of more than 1,400 kinds, all of which are handwritten by Dongba priests with bamboo pens. Due to the ...
