关于Steerable filtering decomposition 的matlab程序,- STEERGAUSS Implements a steerable Gaussian filter. This m-file can be used to evaluate the first directional derivative of an image, using the method outlined in: W. T. Freeman and E. H. Adelson

基于高斯滤波器的可控金字塔的方向滤波器，对学习方向滤波的同学很有帮助-Gaussian filter based on the direction of the pyramid steerable filter

Implements the 1st and 2nd order Gaussian derivative steerable filter in matlab.The oriented first order derivative can be obtained by taking the dot product of a unit vector oriented in a specific direction with the gradient. The basis filters are
