Wavelet Transform Implement Image Steerable Filter

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 images 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.
