| Abstract | Recent advances in three dimensional display technologies and the growing efforts put in the production of three dimensional videos are intensely demanding for new, more efficient three dimensional content representation formats. One promising format is the so-called multiview plus depth format where multiple views of the observed scene are represented together with a per pixel depth map. Naturally, this format requires to efficiently code not only the video views but also the depth data. In this context, this paper proposes a novel depth map codec encoding the depth data by means of a binary tree triangular decomposition and reconstructing the depth map values by means of a triangle based planar approximation. For depth maps related to typical three dimensional video contents, the proposed depth map codec outperforms both the H.264/AVC standard with all intra coding modes enabled and the JPEG standard. In particular, for the same objective reconstruction quality, the proposed codec allows an average bitrate reduction of 60% and 90% regarding H.264/AVC Intra and JPEG coding, respectively. |

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.
