玻璃缺陷特征提取

The Feature Extraction of Glass Defection

根据玻璃缺陷的特点,研究了玻璃缺陷图像特征提取的基本原则,有效提取了玻璃图像中的缺陷目标的几何特征及7个不变矩特征.通过特征有效性分析,选取每幅玻璃缺陷图像的几何特征作为识别参数,实验结果表明,提取的特征区分度良好.

According to the properties of glass defect image,the basic principle of feature extraction is studied for glass defect image in the paper.Geometrical characteristics and seven moment invariants are extracted for defect target in glass image.Geometrical characteristics is selected to pattern recognition by validation analysis.The experimental results show that the distinguishing effect is good the extracted feature in this paper.
