| 摘 要： | 根据可操纵小波多分辨率分析的原理,将小波多分辨率分析与方向微分算子相结合,设计实现了基于二维多方向微分的小波滤波器组,提出了分辨率及方向均可调节的图像边缘检测方法。该方法具有计算效率高、抗带间混叠及多方向选择等特点。通过仿真试验并将其与canny算法和传统的B样条小波边缘检测算法进行比较,验证了该方法的有效性和优越性。

| Abstract: | Based on the steerable wavelet multi-resolution principle,combining wavelet multi-resolution analysis and directional derivative operator,and improving the frequency property of filter,the two-dimensional multi-directional derivative wavelet filter bank was designed.And a resolutional and directional adjustable method of the image edge detection was proposed,which is characterized by high efficiency of computation,anti-inter-band aliasing,and multi direction option.By simulink experiment and comparison with canny and traditional B-spline wavelet image edge detection arithmetic,the efficiency and superiority of this method are proved. |
