| Abstract | This proposal deals with the topic of tracking an unknown number of persons with a monocular camera in indoor environments. Within this context the main tracking system requirements are defined not only by a robust determination of all human trajectories but also by a reliable recovery of all object identities especially for challenging situations like heavy occlusion or the reentry of a person. Regarding all these needs a novel approach has been developed combining a probabilistic particle filter framework with an heuristic simulated annealing technique ported to the tracking domain. While the inter frame correspondence of objects, i.e. the assignment of identities, is handled by the simulated annealing approach, the particle filter architecture will be responsible for both the classification of an object to be a person as well as a stable tracking of the respective trajectory. An active shape model is utilized to create weights for the particles and thus serves as an object classifier. Our system has been evaluated on several video sequences showing meeting scenarios with a different number of participants. Quantitative numbers based on a tracking evaluation scheme show, that our system is capable of not only accurately determining the number of persons visible in each scene but also of precisely tracking each human and correctly assigning a label. |

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.
