Abstract—This paper presents an overview of color and texture
descriptors that have been approved for the Final Committee Draft
of the MPEG-7 standard. The color and texture descriptors that
are described in this paper have undergone extensive evaluation
and development during the past two years. Evaluation criteria include effectiveness of the descriptors in similarity retrieval, as well
as extraction, storage, and representation complexities. The color
descriptors in the standard include a histogram descriptor that is
coded using the Haar transform, a color structure histogram, a
dominant color descriptor, and a color layout descriptor. The three
texture descriptors include one that characterizes homogeneous
texture regions and another that represents the local edge distribution. A compact descriptor that facilitates texture browsing is
also defined. Each of the descriptors is explained in detail by their
semantics, extraction and usage. Effectiveness is documented by
experimental results.
