| Abstract | In this paper, we propose an efficient and embedded 3-D wavelet video coding algorithm, which exploits inter- and intra-subband correlations along spatial and temporal directions through the use of spatio-temporal orientation trees. The spatio-temporal tree structure has nodes as a block of ntimesn coefficients as a basic unit in contrast to a single coefficient in the 3-D SPIHT. The proposed algorithm combines the benefits of both 3-D zerotree and zeroblock based coding approaches in a single algorithm. This not only helps in exploitation of both inter- and intra-subband correlations efficiently but also results in better aggregation of zerotrees. Simulation results show the improved performance of the proposed coder over a 3-D SPIHT coder for the test sequences considered. Like 3-D SPIHT, the proposed algorithm posses all its functionalities such as fully embedded bit stream, precise rate control and multi-resolution scalability. |

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.
