Embodiment Construction

[0096] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0097] The theoretical principle on which the denoising method of the present embodiment is based is: Chinese characters in China are all composed of some simple basic strokes or deformations of these basic strokes, and the most basic strokes include: dot, horizontal, vertical, left, right ,Such as figure 1 shown. Through observation, it can be found that these basic strokes have the following two characteristics: 1) the width of the strokes changes continuously; 2) the strokes have obvious directions. The noise in stele images has the characteristics of random distribution, and the noise width is generally smaller than the stroke width.

[0098] In this embodiment, based on the above-mentioned differences between strokes and noise, an integrated denoising method for stele images is proposed. First, bilateral filtering is used to smooth the...

Abstract

The invention discloses an integrated denoising method of inscription-like images. The method comprises the following steps: performing smoothing processing on input inscription-like images to be processed by use of a double-side filtering method; performing enhancement processing on the images subjected to the smoothing processing successively by use of a top hat transformation method and bottom hat transformation method; carrying out binary processing on the images subjected to the enhancement processing by use of an Ostu method; and performing denoising processing on the images subjected to the binary processing by use of a mixed method of run-length statistics and area communication to obtain denoised inscription-like images. The integrated denoising method of the inscription-like images solves the problem of excessive denoising of the inscription-like images in the prior art.

Description

technical field [0001] The invention belongs to the technical field of image processing, and relates to an integrated denoising method for stele images. Background technique [0002] Inscriptions are an important carrier and form of preservation for the inheritance of ancient Chinese calligraphy. Along with the use and development of Chinese characters, the inscriptions that have been handed down to this day have gone through thousands of years, and interpret the connotation of traditional Chinese culture with their unique artistic forms and artistic language. It is of great value to the study of Chinese culture. At present, most of these inscriptions are stored in real objects, but due to the strict environmental requirements for physical storage, although people have taken many measures to solve environmental problems, as time goes by, various inscription works will still appear such as fading, bleeding, paper, etc. Qualitative discoloration, brittleness, cracks, mildew a...
