A Review of Fabric Defect Detection Techniques

In modern manufacturing industries quality inspection is an important aspect. For a long time, fabric defect inspection process is carried out by human visual inspection hence it is insufficient and costly. Therefore, automatic fabric defect inspection is required to reduce the cost and time waste caused by defects. The development of fully automated web inspection system requires robust and efficient fabric defect detection algorithms. Various techniques have been developed to detect fabric defects. Categorization of fabric defect detection techniques is useful in evaluating the qualities of identified features. Therefore on the basis of nature of features from the fabric surfaces, the proposed approaches have been characterized into three categories; statistical, spectral and model-based
