织物疵点图像的特征参数提取

疵点图像的特征提取是识别织物疵点的重要依据,它直接影响疵点识别的效率和准确率.基于特征参数应具有灵敏度高、独立性强、运算快的特点,提取出疵点的区域面积、边界周长、中心点坐标、长短轴长度、形状参数F和离心率E作为疵点的特征参数.实验证明它能够识别出大部分常见疵点,并为疵点定位标识提供充分依据.

The Feature Extraction of the Fabric Defects Image

The feature extraction of the fabric defects image is an important basis in the fabric defects 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,they 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.
