Abstract
In this paper, we propose a simple but efficient method to identify the correct repeat unit in a yarn-dyed fabric weave pattern and color pattern automatically, especially when they contain error pattern recognitions. With only the color pattern of the fabric to be detected, our method can solve three problems simultaneously, even though there are errors in color pattern recognition. The method extracts the weave/color repeat unit, identifies the full weave pattern, and locates and rectifies the misrecognition in color pattern if there is one. The layout of color yarns is obtained by statistical solution. The weave pattern is partly determined by the correlation between color pattern and weave pattern, while that left can be identified by tentative grouping. In this process, the weave repeat unit is obtained when every group achieves internal uniformity; moreover the misrecognition in color pattern can be located and rectified simultaneously. Finally, the color repeat unit can also be extracted in the same way. Experiments on real fabrics validate the effectiveness of our method in extracting weave/color repeat unit from color pattern which contains errors.
