| Abstract | In this paper, a method for real-time tracking of moving objects or pedestrians is proposed. Especially, we tackled to track an object whose part was temporally occluded or which traversed in front of the cluttered background. Furthermore, we tried to obtain the accurate trajectory of the center of it stably even then. For the problems, we present a probabilistic color-based tracking. In our proposed method, we incorporated particle filtering into graphical models and applied it to the color-based tracking. When the color histogram of the tracked object was made, we used not one region of the whole of the object but the multi-part region of it if it was divided in some parts (e.g. the head and the body of a pedestrian). We treated the multi-part region as a graphical model. In the graphical model, messages about the state of the parts are sent to other parts. As the result., even when the tracked object has occluded part, our proposed method can track it stably and infer the state (e.g. position) of the occluded part. We made experiments to confirm effectiveness of this proposed method. |

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.
