| Abstract | Dual weight of belief and plausibility have been introduced to cope with fusion problem of multi-modal features in observation process within a framework of track-before-detect visual tracking by particle filter for multiple target. Observation model consists of dual function of belief and plausibility corresponding to conjunction and disjunction of multi-modal features. Each particle has dual weight corresponding to the two likelihood functions, and the two weights are updated respectively. Resampling step involves some elaborations consisting of three steps such that; 1) normalized weights of plausibility are used as the probability to draw with replacement, 2) uniform value is set for the weights of plausibility after the draw with replacement, and 3) weights of belief are adjusted for each particle. The idea of dual weight has been extended to multiple target tracking framework with SMC-PHD filter. Performance of the proposed method has been demonstrated for multiple people tracking over videos captured by a fish eye camera at ceiling. |

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.
