Abstract. This work describes the feature extraction module of a system designed to measure and interpret optical refractive errors (astigmatism, axis of astigmatism, near- and short-sightedness) from Hartmann-Shack (HS) images. This module uses the Gabor wavelets transform to produce a reduced set of features from an image of the human eye that are then input to an image analysis module based on Support Vector Machines.
