DetectionMethodofFabricDefecBasedonWaveletEntropy.
- 在采用二维离散小波变换对织物图像进行分解的基础上,引入了熵的概念,将小波熵作为织物图像的特征值,把熵值看作系统紊乱程度的度量,由此得到织物图像的小波熵特征值,通过与正常织物经过二维小波变换后提取的小波熵值相比较,熵值大者即认为有疵点存在-At the use of two-dimensional discrete wavelet transform decomposition of the fabric image, based on the introduction of the concep
HoughTrans
- Hough变换的实质是将图像空间内具有一定关系的像元进行聚类,寻找能把这些像元用某一解析形式联系起来的参数空间累积对应点。在参数空间不超过二维的情况下, 这种变换有着理想的效果。但是,一旦参数空间增大,计算量便会急剧上升,同时耗费巨大的存储空间,耗时也随之猛增。就此,多年来国内外众多学者针对具体情况对常规Hough变换进行了多方面的探索,并提出了许多有价值的改进方法。-Hough transform is essentially the image space has a certain rel
