| Abstract | This paper describes a set of data structures that enables the tracking of large scale data sets. Although well-known procedures exist for speeding up tracking performance, such as gating, they are typically not sufficient for situations where it is required to simultaneously track tens or hundreds of thousands of targets where even the gating calculations themselves take a significant proportion of time. We describe dynamic spatiotemporal binary tree-based structures, a box forest and cone forest, for storing measurements and tracks, and a string trie for text information. Efficient pruning of the structures allows for a vast reduction in the number of gating calculations. Performance of a real-time tracking algorithm that uses the data structures is demonstrated on a real-world maritime data set of more than 100,000 targets. |

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.
