| Abstract | Mean shift is a nonparametric estimator of density gradient. Traditional mean shift algorithm is rather sensitive to the influence of background. Therefore, an improved mean shift object tracking algorithm is proposed. Firstly, a novel weights given method is given, which improves the kernel function. The method is that the pixels which near the centre of object are given biggest weights, and the pixels which at the edge of the object are given by exponent distribution as a result of occlusion. In order to hand the occlusion, the occlusion detecting method based on sub-block detecting is also established. The novel sub-block detecting algorithm is that the tracking window is divided into two parts, including right and left, and the similarity measure is calculated respectively. The simulation results show that the improved mean shift algorithm can hand the occlusion effectively and track the moving object very well, and it can track moving object more powerful than the basic mean shift tracked. |

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.
