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 ap

Example of a two-dimensional Gabor filterIn image processing, a Gabor filter, named after Dennis Gabor, is a linear filter used for edge detection. Frequency and orientation representations of Gabor filter are similar to those of human visual system,
