Simulation method of embroidery art style based on non-realism

Abstract

The invention discloses a non-realistic embroidery art simulation method. First, convert the input static two-dimensional embroidery image into a grayscale image, and add noise points according to the local grayscale value of the image to obtain a noise image; then find the curve direction of the noise image, and apply noise to each pixel along the curve direction. Point convergence processing is performed to obtain the embroidery line texture; then, the edge image is superimposed on the embroidery line texture image to obtain the embroidery texture image; again, the embroidery texture image is subjected to concave-convex processing to obtain the embroidery texture image with 2.5-dimensional stereoscopic visual effect; finally, Input background images such as different fabrics, and fuse the embroidery texture image with the background image to obtain the final embroidery artistic effect image. This method simulates the embroidery of ethnic minorities, and is based on the extraction of image embroidery lines and the generation of three-dimensional visual effects.

Description

technical field [0001] The invention belongs to the field of information technology, and in particular relates to a non-realistic-based embroidery art simulation method for ethnic minorities. Background technique [0002] Non-photorealistic rendering (NPR: Non Photorealistic Rendering) technology is a research direction proposed by graphic workers in the 1990s, and is a hot issue in computer vision and graphic image processing. Non-photorealistic drawing combines artistic drawing rules and scientific technical methods. It uses computers to generate graphics with hand-painted styles such as cartoons, oil paintings, and watercolors. It mainly expresses the artistic characteristics of graphics and simulates works of art. It plays an increasingly important role in the simulation of natural artistic style, the enhancement of image information, the generation of animation, the artistic expression of data, and medicine, architecture, and education. With the improvement of technolo...

Problems solved by technology

At present, researchers have simulated the works of the four famous embroideries such as Suzhou embroidery and Hunan embroidery through genetic algorithms, color mixing principles, and grid division. However, there are not many style simulations for ethnic minority embroidery such as Miao embroidery, Yi embroidery, and Dong embroidery. See
