| Abstract | Describes a fast block-matching algorithm (BMA) for motion estimation exploiting the center-biased motion vector distribution characteristic more efficiently than the center-biased hybrid search (CBHS) algorithm does. This proposed algorithm, which is called the "fast center-biased hybrid search" (FCBHS), employs a hybrid method of a compact plus-shaped search, an X-shaped search and a diamond search to reduce the search point for motion vectors which are distributed within a 2-pixel radius of the center of the search window. Experimental results show that the FCBHS algorithm is about 44 times faster than a full search and 7-10% faster than the CBHS algorithm. Such a fast sub-optimal motion estimation algorithm is essential for situations which have limited processing power and constraints on the amount of power consumption, like real-time mobile video coding applications. This paper compares the popular sub-optimal block-matching technique with FCBHS, for which both the processing speed and the accuracy of motion compensation are tested over widely-used H.263 test video sequences. |

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.
