Auto-TLDR; Local Binary Quaternion Rotation Pattern for Color Texture Classification
Color is very important feature for image representation, it assumes very essential in the human visual recognition process. Most existing approaches usually extract features from the three color channels separately (Marginal way). Although, it exists few vector expressions of texture features. Aware of the high interaction that exists between different channels in the color image, this work introduces a compact texture descriptor, named Local Binary Quaternion Rotation Pattern (LBQRP). In this LBQRP purpose, the quaternion representation is used to represent color texture. The distance between two color can be expressed as the angle of rotation between two unit quaternions using the geodesic distance. After a LBQRP coding, local histograms are extracted and used as features. Experiments on three challenging color datasets: Vistex, Outex-TC13 and USPtex are carried out to evaluate the LBQRP performance in texture classification. Results show the high efficiency of the proposed approach facing to several stat-of-art methods.
