Computer-assisted disordered needlework manufacture method based on reaction diffusion process

Abstract

The invention discloses a computer-assisted disordered needlework manufacture method based on a reaction diffusion process. The manufacture method comprises the following steps of a step 1 that a color image is taken as an input, and different object regions, regional vector fields and image obviousness of the input color image are extracted by adopting image segmentation, regional vector field extraction and image obviousness computation methods; a step 2 that a three-layer parameterization stitch model comprising single embroidery threads, single cross needles and cross needle distribution is built according to the characteristic of a disordered needlework, and a parameter value computation method of a cross needle distribution layer in the model is described; a step 3 that a stroke neighbourhood graph is built according to the initial needle tracking sequence generated by each object region, the direction, the length, the color hue, the color saturation and the color brightness of the generated needle tracking sequence are respectively controlled by adopting five reaction diffusion processes, the colors of embroidery threads are selected, and the final needle tracking sequences of all object regions are obtained; a step 4 that coordinates of the needle tracking sequences are converted into coordinates of a computerized embroidery machine.

Description

technical field [0001] The invention relates to a method for making computer-aided random stitch embroidery, which belongs to the technical fields of computer image processing and computer graphics. Background technique [0002] Random stitch embroidery is a new embroidery art created by combining painting theory and embroidery theory. She was founded in the 1930s by Ms. Yang Shouyu, a contemporary embroidery artist. The traditional embroidery is "closely connected with its needles, compared with its lines" plane embroidery, but allows the author to freely express his thoughts and feelings, and embroiders a three-dimensional picture with crisscross, different lengths, dense overlapping, flexible and changeable stitches , to realize the organic combination of "painting theory" and "embroidery theory". Most of the producers of random stitch embroidery are based on real life, with a wide range of topics, strong visual and spatial awareness, visual and psychological images, bri...

AI Technical Summary

Problems solved by technology

However, random stitch embroidery mainly uses the changeable arrangement direction of needles and threads, the length of needles and threads, and the flexible and changeable use of color to express objects, and these methods cannot be directly applied to the process of making random stitch embroidery.
