| Abstract | Person re-identification (re-ID) is the ability to associate the identity of a person observed at one time and location with the same subject when acquired at a different time and location. Trajectory forecasting is the task of predicting the likely path that a person might take to reach a destination. Contextual trajectory forecasting (CTF) leverages the 3D geometric information of the environment along with observed behavioral norms for human path prediction. Re-ID involves feature matching to find an identity in the database with similar features. The features encompass information regarding appearance of the person like color and texture, or context of the scenario like the time and location of the human subject. CTF provides a future estimate of the likely time and spatial location of previously observed subjects. Embedding this information into traditional re-ID algorithm significantly boost their performance. In this paper, re-ID is performed across non-overlapping cameras with real world human subjects. CTF is embedded into a re-identification algorithm that uses symmetry driven accumulation of local features (SDALF) [1] to evaluate the performance. Experiments suggest a significant improvement in re-identification by embedding CTF. |

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.
