Embodiment Construction

[0033] The specific content of the present invention will be further explained in detail below in conjunction with the examples.

[0034] refer to Figure 1-8 , the present embodiment provides a method for extracting line drawings of high-resolution opera costumes, comprising the following steps:

[0035] Step 1, input a high-resolution opera costume image I, such as image 3 Shown; The present invention no longer limits to the image size of input, can process image data above 100M;

[0036] Step 2, carry out lossless compression, denoising to image I (get as Figure 4 The image shown) and sharpening preprocessing work to reduce the resolution of the image, increase the running speed and reduce the video memory requirement, and obtain the image I ′ ,like Figure 5 shown;

[0037] Among them, the denoising point uses non-local mean denoising to denoise the image, and the non-local mean filtering draws on the phenomenon that the more images are weighted, the better the effe...

Abstract

The invention discloses a line graph extraction method for high-resolution opera costume. The method comprises the following steps: step 1, inputting an opera costume image I; step 2, carrying out preprocessing work of lossless compression, denoising and sharpening on the image I to obtain an image I '; 3, extracting an image contour of the preprocessed image I'by using a binary image contour extraction method to obtain an image I ''; and step 4, carrying out line graph extraction on the image I ''by using a LineDistister deep network added with a batch processing module to obtain a final traditional opera costume line graph I'' '. According to the method, the high-resolution traditional opera costume line graph extraction effect is greatly improved, and meanwhile, the line graph extraction efficiency is greatly improved through a batch generation mode. A fine line graph extraction result can be realized only by means of a picture shot by convenient equipment such as a mobile phone camera, and the problems of fuzzy clothes line graph extraction and incomplete line graph extraction texture removal are solved.

Description

technical field [0001] The invention relates to computer graphics processing technology, in particular to a method for extracting line graphs of high-resolution opera costumes. Background technique [0002] Qin Opera originated in Shaanxi and Gansu in ancient times, and is one of the most expressive genres of traditional Chinese drama. The art of Qin Opera has a history of thousands of years of inheritance in my country. It can be called the originator of Chinese opera and plays a vital role in the integration, development and evolution of Chinese opera. The classical opera costumes of Qin Opera are made of cloth, tribute, and kudzu, etc. Most of the colors of these materials are bright and bright, which can make the characters in the opera appear magnanimous and gorgeous on the stage. The pythons, backs, gowns, and pleats worn by performers in some major plays are mostly embroidered with multicolored patterns, and their patterns are simple and colorful. The unique three-p...
