摘要
从空间剖分的角度，滤波的观点和几何尺度分析对正交离散小波变换做了较详尽说明．分析了小波的选择对边缘检测的影响．且以医学中各器官的图像检测这一实际问题为背景，选择了适当的小波，给出了边缘检测的算法流程及计算机仿真结果．从算法流程结果表明，该算法具有计算复杂度低、抗噪声能力强等特点．
The application of the two-dimensional discrete wavelet transform to imageedge detection is discussed. It is approved that a set of zero-antisymmetrical waveletbase functions are suitable for the step edge detection. Application in medical imageedge detection and experimental results are also given to show the effectiveness.
