| Abstract | Depth-based 3D formats for state of the art High Efficiency Video Coding standard facilitate the synthesis of virtual views with a brief binary representation. Depth maps coding error results in synthesis artefacts for virtual views rendered during Depth Image Based Rendering (DIBR) process. Based on depth maps distortion, synthesized view distortion estimation models are integrated in 3D-High Efficiency Video Coding (3D-HEVC) to cater the synthesis artefacts. This paper presents complexity and implementation analysis of synthesized view distortion estimation model integrated in Emerging 3D-HEVC standard. Profiling of the reference software of 3D-HEVC is performed and computational hotspots are identified based on the profiling information. Profiling results show that the Renderer model integrated in 3D-HEVC, for Rate Distortion Optimization (RDO) of depth maps coding by estimation of synthesized view distortion, takes about (18-26%) of total encoding time and is identified as one of the computational complex part of the 3D-HEVC standard. Algorithmic and implementation complexity analysis of the renderer model is presented in this paper. |

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.
