Abstract | Mean-shift is an effective algorithm for object tracking. However, it has a poor performance when the illumination condition changes fast or the tracking target being shadowed. By contract, particle filter based object tracking has a better tracking performance, but the tracking speed is much slower compared to mean-shift. Owing to the limitations of just using a single algorithm, a novel object tracking method based on both mean-shift and particle filter is proposed in this paper. A system with feedback has been constructed by the proposed method, in which the mean-shift technique is used for initial registration, and the particle filter is called to improve the performance of tracking when the tracking result with mean-shift is unconvincing. RGB color histogram is exploited as image feature and Bhattacharyya coefficient is used for measuring the similarity between object model and candidate regions. Tracking experiments evaluated on various videos show that the proposed method is well-behaved in cases that objects have shift-variant, rotation and scaling, and achieves a satisfying tracking speed. |

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.
