Knitted fabric structure recognition based on deep learning

In knitted fabric structure recognition, the recognition rate is influenced by uneven light, fabric hairiness, fabric rotation, fabric thickness variation, yarn deviation, and loop deformation. To solve this problem, a method for recognizing knitted fabric structure based on deep learning is proposed. Firstly, sample images of fabrics are captured and a knitted fabric structure image database is established. Secondly, based on deep convolution neural network and transfer learning, the bvlc_reference_caffenet model trained by AlexNet is used as the pre-trained network. Then the pre-trained parameters of the network are transferred to the target data-set and the network is trained. Finally, the knitted fabric structure is recognized by the trained network. Experiment results show that the proposed recognition method is robust, which can overcome the influence of fabric rotation, fabric hairiness and uneven light, and achieves a high recognition rate.
