| Abstract | In this paper we combine model-based video synthesis with block-based motion-compensated prediction (MCP). Two frames utilized for prediction where one frame is the previous decoded one and the other frame is provided by a model-based coder. The approach is integrated into an H.263-based video codec. Rate-distortion optimization is employed for the coding control. Hence, the coding efficiency does not decrease below H.263 even if the model based coder cannot describe the current scene. On the other hand, if the objects in the scene correspond to the model-based coder, significant gains in coding efficiency can be obtained compared to TMN-10, the test model of the H.263 standard. This is verified by experiments with natural head-and-shoulder sequences. Bit-rate savings of about 35% are achieved at equal average PSNR. When encoding at equal bit-rate, significant improvements in terms of subjective quality are visible. |

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.
