Description: Gabor wavelet transform applied to feature extraction of ophthalmic images. We investigate a new approach for measuring ocular refractive errors (astigmatism, near-sightedness and shortsightedness) from images of the human eye [1]. This approach uses Support Vector Machines (SVMs) to analyse data features extracted from images of the eye acquired with a technique known as Hartmann-Shack [2] and output measures for the eye´ s refractive errors. Prior to analysis and feature extraction an image processing stage takes place to identify and crop the region of interest considering domain spatial and geometrical information. Then a set of relevant image features are extracted using wavelet and Garbor Transforms. These features are finally fed into a SVM module for analysis that provides a diagnosis of refractive errors present in the ocular globe under investigation.
