When you stack the filter responses you get a per-pixel feature vector. Each pixel in the image grid is a separate datapoint, and each plane in the variable featureSet is a separate feature. A two-dimensional Gabor function consists of a sinusoidal plane wave of some frequency and orientation, modulated by a two-dimensional Gaussian [3]. We review commonly used feature reduction techniques (in Section 3.2 and 3.3), which we are going to employ for extracting different types of Gabor features.We have observed (in our experiments) that different methods have quite a different impact on the recognition rate.
