Assembly Automation, Volume 36, Issue 2, April 2016. Purpose We proposed a biologically inspired processing architecture to recognize and classify fabrics with respect to the weave pattern (fabric texture) and yarn color (fabric color) Design/methodology/approach By using the fabric weave patterns image identification system, this study analyzed the fabric image based on the HMAX model of computer vision, to extract feature valuesrelated to texture of fabric. RGB color descriptor based on opponent color channels simulating the single opponent and double opponent neuronal function of the brain is incorporated in to the texture descriptor to extract yarn color feature values. Finally, Support Vector Machine (SVM) Classifier is used to train and test the algorithm. Findings This two-stage processing architecture can be used to construct a system based on computer vision to recognize fabric texture, and to increase the system reliability and accuracy. Using this method, the stability and fault-tolerance (invariance) was improved. Originality/value Traditionally, fabric texture recognition is performed manually by visual inspection. Recent studies have proposed automatic fabric texture identification based on computer vision. In the identification process, the fabric weave patterns are recognized by the warp and weft floats. However, due to the optical environments and the appearance differences of fabric and yarn, the stability and fault-tolerance (invariance) of the computer vision method are yet to be improved. By using our method, the stability and fault-tolerance (invariance) was improved.
