Simulation Research For Miao Nationality Embroidery Art Style

In the field of non-photorealistic rendering technology,the method of simulating the style image has now matured.In recent years,many researchers have successfully simulated artistic works such as pencil painting and oil painting using digital simulation technology.In the art handicrafts,there are many stylized simulation techniques for the nationality,but the digital simulation of the Miao embroidery style is rare.Miao embroidery was selected as a national intangible cultural heritage in 2006.It is a typical representative of the history and culture of the Miao nationality and an important part of the Miao costume culture.With the development of the times,there are fewer and fewer people in Miao embroidery craftsmanship.Culture needs to be passed down and carried forward.In view of the characteristics of real Miao embroidery,this thesis carried out a digital simulation study of Miao embroidery art styleThis thesis focuses on five aspects:image contour extraction,seedling embroidery texture generation,image segmentation,image fusion and color transmission.The pattern with Miao characteristics is selected as the input image,and the image is simulated by Miao embroidery stitching.Then the generated Miao embroidery stitch texture is segmented and merged with the edge contour of the image to achieve digital simulation of Miao embroidery style.This thesis works as follows:(1)Miao embroidery is first filled with embroidery lines to outline the contours For this feature,after the input image is grayed out,the edge extraction algorithm is used to extract the contours of the images to obtain the edge contours.(2)According to the characteristics of the needlework of Miao embroidery,the improved line integral integration convolution algorithm(Line Integral Convolution,LIC algorithm for short)effectively simulates the stitch texture of the flat embroidery method in the Miao embroidery technique,and uses the image segmentation to obtain the needle.The foreground and background of the trace texture image are separated,preserving the foreground texture of the image.The edge contour of the image is blended with the foreground texture to obtain a grayscale image with a Miao embroidery style.(3)For the gray image of Miao embroidery style,the color information of the input image is transmitted to the simulated gray image on the HSV color space to realize the color transmission of the Miao embroidery style image.(4)According to the selection characteristics of Miao embroidery cloth,the image of real embroidered cloth is selected as the background image,and the method of fusing the miao embroidery pattern with the background image is used to realize the simulation of Miao embroidery.Miao embroidery style,as well as seedlings close to the real seedlings.Embroidered style image.(5)The experimental results of this thesis were analyzed.The choice of image stitch length was analyzed and discussed.The resulting image is compared to real seedling embroidery.The texture image produced by the improved noise point and the texture image produced by the white noise are compared and analyzed.The experimental results show that the algorithm can simulate the effect of real embroidery,which is a useful complement to non-photorealistic rendering,and is conducive to the protection and inheritance of national culture.
