The first function named "gaborFilterBank.m" generates a custom-sized Gabor filter bank. It creates a UxV cell array, whose elements are MxN matrices; each matrix being a 2-D Gabor filter. The second function named "gaborFeatures.m" extracts the Gabor features of an input image. It creates a column vector, consisting of the Gabor features of the input image. The feature vectors are normalized to zero mean and unit variance. At the end of each file there is a Show section that plots the filters and shows the filtered images. These are only for illustration purpose, and you can comment them as you wish.
