Computer-aided disordered needlework manufacture method using genetic algorithms

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...

Problems solved by technology

However, these attributes of cross needles are often related to multiple image features, and the dependencies between them are complex. It is difficult to establish the display function relationship between the cross needle attributes and image features. Therefore, it is necessary to define the drawn needle The evaluation function of the trace scheme image uses a random search method such as a genetic algorithm to solve this problem.

However, the method used in the existing work only involves a single image feature, and the evaluation method of the drawing result does not meet the evaluation requirements of random stitch embroidery, and its definition of the stroke model does not conform to the cross stitch as the basic method in random stitch embroidery.
