AN APPARATUS FOR RETRIEVING AN IMAGE TEXTURE DESCRIPTOR FOR DESCRIBING TEXTURE FEATURES OF AN IMAGE

摘要

A method for retrieving an image texture descriptor for describing texture feature of an image, including the steps of (a) filtering input images using predetermined filters having different orientation coefficients;(b) summing up and normalizing the pixel values of the filtered images onto axes of each predetermined direction to obtain data groups consisting of average of directional pixel values; (c) selecting candidate data groups among the data groups by a predetermined classification method; (d) determining a plurality of indicators based on orientation coefficients of the filters used in filtering the candidate data groups; and (e) determining the plurality of indicators as the texture descriptor of the image.
