Abstract

In a Gabor filter, a modified Gabor mask function is generated from an original Gabor mask function. A convolution of an image is performed with the modified Gabor mask function to generate a filtered image. The modification of the original Gabor mask function to the modified Gabor mask function reduces a number of calculations during such a convolution.
