GABOR FILTER AND FILTERING METHOD THEREOF, AND IMAGE PROCESSING METHOD ADOPTING THE SAME

A Gabor filter, a filtering method thereof, and an image processing method using the same are provided to perform filtering in real time in embedded environment. The first mask generating unit(40) generates a Gabor filter mask whose central frequency is moved by pi with regard to at least one or more axes of an x-axis and a y-axis. The first filtering unit(50) performs the convolution of an input image and the Gabor filter mask. The first mask generating unit(40) generates one of the Gabor filter mask of the first type and the Gabor filter mask of the second type to perform the convolution of the input image by a certain data unit. The Gabor filter mask of the first type has valid data corresponding to 1/2 of the number of the convoluted data. The Gabor filter mask of the second type has valid data corresponding to 1/4 of the number of the convoluted data.
