Embodiment Construction

[0042] The invention discloses a method for making computer-aided random stitch embroidery using a genetic algorithm, such as figure 1 As shown, the main flow of each embodiment part is introduced respectively below:

[0043] 1. Image feature extraction

[0044] The present invention extracts the corresponding image features as the basis for subsequent random stitch embroidery stitch sequence generation. As described in step 2, the image features extracted by the present invention mainly include object area, area vector field and image saliency feature The three are described step by step below.

[0045] 1.1 Object Region Extraction

[0046] In the embroidery process of chaotic stitch embroidery, the embroidery method is different for different object areas. In the foreground area, the stitch density is higher and the embroidery thread length is shorter. Therefore, in the process of making random stitch embroidery by computer, it is necessary to divide the image into differ...

Abstract

The invention discloses a computer-aided disordered needlework manufacture method using genetic algorithms. The method includes the steps of firstly, using an input color image as a reference image, and using imaging segmentation, area vector field extraction and image consistency line extraction to extract image features such as different object areas, area vector fields and image saliency; secondly, defining three-layer parameterized knitting models including each embroidery thread, each cross needle and cross needle arrangement according to features of disordered needlework, and describing a method for obtaining embroidery thread collection according to the parameterized knitting models; thirdly, using the genetic algorithms to obtain disordered needlework needle tracking sequence according to knitting model parameters determined according to image features; fourthly, converting needle tracking coordinates into coordinates required by a computerized embroidery machine, and inputting the coordinates into the computerized embroidery machine to obtain the corresponding disordered needlework. The method is significant to mechanical standardized production of the disordered needlework.

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. Specifically, this method defines and constructs a stitch model suitable for random stitch embroidery, and extracts image features from color images, and uses genetic algorithm to automatically determine the stitch model parameters based on image features to complete the random stitch embroidery production process . Background technique [0002] Random stitch embroidery is an embroidery art created by Changzhou artist Professor Yang Shouyu in the 1930s. It reformed the traditional embroidery method and combined it with the brushstrokes and colors of Western paintings. Embroidery expression method. Random stitch embroidery is free in needle movement, flexible in color use, and has a large room for display. It changes the traditional embroidery stitch method of "closely connectin...
