TEXTURE DESCRIPTION METHOD AND TEXTURE-BASED IMAGE RETRIEVAL METHOD USING GABOR FILTER IN FREQUENCY DOMAIN

摘要

A kind of texture description method describes the texture information of image using Gabor filter in frequency domain comprising: one first step of converting image, wherein the image of the time-domain of image is converted to frequency domain; Second step, the image frequency domain for filtering transformation have N*M filter fields using Gabor filter, and wherein N and M is scheduled positive integer; Third step, the Gabor filter for extracting characteristic value image in Andrea Gabor filter of the frequency domain division layout of each channel corresponding to the filter sections N*M; And four steps, the image that description is accorded with using the describing texture of image of the texture eigenvalue.
