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 concept of entropy, wavelet entropy as a fabric image of the characteristic values, the entropy as a measure of the degree of system disorders, the resultant fabric image of the wavelet eigenvalues entropy, through the fabric after normal after the extraction of two-dimensional wavelet transform of the wavelet entropy values compared to the larger entropy that has faults exist
