Problems solved by technology

Chung-Feng Jeffrey Kuo, Kuo et al proposed an automatic repetitive pattern detection framework consisting of sub-pattern image clustering and geometric segmentation, specifically for gray printed fabrics using a fuzzy C-means clustering algorithm and a specific cluster validity criterion The pattern image, and then the repeated pattern is segmented by Hough transform, but only handles simple patterns and background scenes such as dot patterns, but cannot handle complex printed fabrics with various patterns

Abstract

An automatic detection method for a minimum repetition unit of a printed fabric image includes scanning printing fabric into an image; manually selecting a rectangular area containing a plurality of pixels in the image, and selecting pixels of at least two vertices as key points; detecting a rectangular sub-image similar to the rectangular area image in the image, marking key points of the rectangular sub-image, adjusting pixel distances to minimize the number of key points, namely similarity points; identifying the minimum repeat units based on the number of similar points. The method can realize the detection of the minimum repetition unit for processing the color printed fabric and the complex printed fabric with various patterns, and greatly reduces the difficulty and workload of colorseparation and plate making.

Description

technical field [0001] The present invention relates to the textile field. More specifically, the present invention relates to a method for automatic detection of the minimum repeating unit of printed fabric images. Background technique [0002] In textile industry automation, the smallest repeating unit (minimum repeating unit area) of printed fabric images is one of the important features that may affect the visual characteristics of textile appearance. Early automatic MRP detection research was carried out based on pattern periodic analysis of computer technology. Wood uses Fourier and related transformations combined with the periodicity of the fabric surface to characterize the carpet pattern, specifically through the angular Fourier power spectrum and autocorrelation function to analyze the periodicity of the weft and warp yarns (yarn spacing) of plain cotton fabrics, focusing more on Spectral analysis of woven fabrics, rather than printed fabrics, is difficult to mig...
