摘要
导向滤波器是一类能够实现图像方向滤波的滤波器组,它比方向滤波器计算量小并且可以实现各个方向的滤波处理。该文把小波函数和多分辨关系引入到导向滤波处理过程中,实现了图像的方向滤波。实验验证了小波可以从图像中提取更多方向的信息,表明新导向滤波的有效性。
Steerable filters are a class of filter banks that can implement oriented filtering,and they have less computation quantity than usual oriented filters and can obtain omni-oriented filtering. This paper introduces the wavelet functions and the multiresolution relationship into the process of the steerable filters, and achieves image＇s oriented filtering. The wavelets can extract more orientation information from images, and the experiments verify the steerable filter, which is designed from the wavelet transform.
