Establishment of enhanced matrix model for fabric image feature

Since the workable model for effective identification of fabric features are not available yet,the result of fabric defect recognition needs to be improved.Thus,this paper has proposed a new fabric image feature model,i.e.,enhanced matrix feature model,which introduces a new enhanced matrix based on the gray of the image.The matrix is made of matrix operators generated by gradient variation of fabric image,which can do transform calculation for pixel value to amplify or reduce the local characteristics of the image so that the image features are displayed clearly.Some programs are compiled to verify this model using MatLab 7.0,and the verification result shows this model is suitable for defect recognition of fabric feature,because the feature variations in the defeat area have been enhanced remarkably.This model has provided a new idea for fabric defect recognition.
