Automatic inspection of simply patterned material in the textile industry

Automatic inspection allows the continuity of the quality of textiles manufacturing, and the optimization of the pinking according to the situation of the defects. A method for defect detection based on a periodicity breaking of the material densitometrical profile is proposed. After the explanation of the method, some important points like texture suppression, image block size choice, and defect characterization are detailed. Finally, the system configuration and the results obtained from the detection stage are introduced.
