TL;DR: In this article, a method for retrieving an image texture descriptor for describing texture features of an image, including the steps of filtering input images using predetermined filters having different orientation coefficients, projecting the filtered images onto axes of each predetermined direction to obtain data groups consisting of averages of each directional pixel values, selecting candidate data groups among the data groups by a predetermined classification method, determining a plurality of indicators based on orientation coefficients of the filters used in filtering the candidates, and determining the plurality of indicator as the texture descriptor of the image.

TL;DR: In this article, an adaptive search method in feature vector space which can quickly search the space indexed based on approximation for a feature vector having features similar to a query vector according to a varying distance measurement is provided.

TL;DR: In this paper, a method of measuring a similarity between images is provided, which includes the steps of computing a statistical dissimilarity between images, computing a perceptual dissimilarities between the images, and computing a dissimilar similarity between the texture features of the images.

TL;DR: In this paper, a method for indexing feature vectors within feature vector data space which includes adaptively forming approximation of the feature vectors on the basis of statistical distribution of feature vectors data within the feature vector space is provided.
