Abstract: In this paper, rotation invariant local binary pattern and local contrast measure have been joined together for describing the texture feature. In addition to this, colour features have also been included in the feature vector of the object tracking algorithm. Thus the texture can be characterised by two orthogonal properties like, the spatial structure (local binary pattern) and the strength of the pattern (contrast). Covariance matrix of the feature vector has been taken as the object descriptor in the proposed algorithm. The performance of the proposed method has been compared by different performance measures, such as the detection rate, tracking speed and coverage test. The proposed method has also been tested for various challenging situations, such as occlusion, camera motion, non-rigidity, and changes in illumination. The experimental results show that the proposed method outperforms the existing methods in terms of performance indices.
