摘要
介绍了一种用于图像纹理奇异性检测的二维数字滤波器的设计,该滤波器是基于离散小波变换设计的。它具有纹理树状结构的多分辨分析特性。用一阶及二阶的微分方法进行奇异点的估计与合并,可应用于图像纹理奇异性检测。
In this paper,a design of 2D-digital tilter.which is based on DWT. used for image texture singularity detection is proposed.It is provided with multiresolution analysis of texture tree construction,method which is using first and second differential,for singularity estimation and combination,can be applied to image texture singularity detection.
