| Abstract | In this paper, we propose a particle filter algorithm with adaptive layered-optimization and multi-feature, which is used for motion-based tracking of natural object. A novel reliability measure based on the particle's distribution in the state space is designed to evaluate the tracking quality. According to the tracking quality, the particle set is divided into two parts: one is optimized to be concentrative for the tracking precision and the other keeps being original for the tracking robustness. The number of particles in each part is decided adaptively by the function which uses reliability score as parameter. This algorithm is demonstrated using the color and orientation features weighted by reliability score. Experiments over a set of real-world video sequences are done and the result shows that this algorithm achieves better performance when occlusion and object-motion in variable direction happen; the consuming time meets the requirement of real-time. |

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.
