摘 要:Segmentation of defect images is an important step in the automatic fabric defect detection.In order to extract fabric defects effectively,a segmentation method of fabric defect images based on pulse coupled neural network (PCNN) model and symmetric Tsallis cross entropy is proposed.The image is segmented by PCNN according to the gray strength difference between fabric defect area and non-defect area.To guarantee that the grayscale inside the object and background is uniform after segmentation,symmetric Tsallis cross entropy is used as the image segmentation criterion to select the optimal threshold and iteration number.A large number of experimental results show that,compared with the related segmentation methods such as Otsu method,PCNN method,the method based on PCNN and cross entropy,the segmentation effect of the proposed method is the best.The texture of non-detect area is removed more completely,and the defect area is segmented more accurately.
