Abstract | Sparse representation has been applied in tracking rapidly. However, most of these methods use the holistic model and grayscale image which result in insensitiveness to color information and ineffectiveness to deformation of non-rigid object. In this paper, we propose a robust and effective tracking method (SRH) based on the block-sparse representation (local information) and HSV color histogram (spatial information). This method not only keeps the merits of block-sparse representation in handling illumination changes and occlusions, but also adds the object color resolution and is not subjected to similar colors interference. It improves the accuracy and efficiency of tracking result. In addition, we calculate the weight of block-sparse representation and HSV color histogram and introduce a fusion method to fuse these two data. Furthermore, the occlusion handling reduces the influence of heavy block, the update strategy guarantees the tracker to adapt to the complex background and morphological changes of target which enhances the reliability of this method. Experimental results compared with several state-of-the-art trackers on challenging sequences demonstrate the robustness and accuracy of the proposed tracking algorithm. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
