Feature Extraction of the Fabric Defects Image

The feature extraction of the fabric defects image is an important basis in the fabric defect identification. It affects directly the efficiency and accuracy of the fabric defects identification. The feature parameter should have high sensitivity, independency and rapid operation, based on this principle, the feature parameters of fabric defects are extracted, which include the area of fabric defects, the boundary perimeter, the center coordinate, the length of the long and short axes, the shape parameter F and eccentricity E. The experiment proved that the size and shape of fabric defects can be identified and the position can be confirmed based on these feature parameters.
