- Abstract
In an automatic bobbin management system that simultaneously detects bobbin color and residual yarn, a composite texture segmentation and recognition operation based on an odd partial Gabor filter and multi-color space hierarchical clustering are proposed. Firstly, the parameter-optimized odd partial Gabor filter is used to distinguish bobbin and yarn texture, to explore Garbor parameters for yarn bobbins, and to accurately discriminate frequency characteristics of yarns and texture. Secondly, multi-color clustering segmentation using color spaces such as red, green, blue (RGB) and CIELUV (LUV) solves the problems of over-segmentation and segmentation errors, which are caused by the difficulty of accurately representing the complex and variable color information of yarns in a single-color space and the low contrast between the target and background. Finally, the segmented bobbin is combined with the odd partial Gabor's edge recognition operator to further distinguish bobbin texture from yarn texture and locate the position and size of the residual yarn. Experimental results show that the method is robust in identifying complex texture, damaged and dyed bobbins, and multi-color yarns. Residual yarn identification can distinguish texture features and residual yarns well and it can be transferred to the detection and differentiation of complex texture, which is significantly better than traditional methods.
