1. A texture description method using a Gabor filter in a frequency domain for describing texture information of an image, comprising: a first step of converting an image, in which an image of a time domain is transformed into an image of a frequency domain; a second step of filtering the transformed image of the frequency domain using a Gabor filter having N×M filtering regions, where N and M are predetermined positive integers; a third step of extracting feature values of the Gabor-filter image in respective channels of a frequency domain division layout corresponding to the N×M filter regions of the Gabor filter; and a fourth step of describing the image texture descriptor using the texture feature values of the image.
