【摘要】 讨论了小波变换在图像边缘检测、分类与描述中的作用，并根据甲襞微循环图像的特点，利用三次样条二进小波，采用Ｍａｌａｔ快速算法进行小波分解，成功地提取了甲襞微循环图像的边缘。更多还原

【Abstract】 In this paper, we discuss the application of wavelet transform to edges detection, classification and description. Then, according to the peculiarity of the nail fold microcirculation images, dyadic wavelet transform is successfully applied to detect the edges and the Mallat algorithm is used in the wavelet decomposition更多还原
