Abstract | Motion estimation is the most important component of any video coding standard. So development of an efficient algorithm for fast motion estimation is the basic need for video encoder design. Block based motion estimation algorithms are used for fast motion estimation as block matching algorithms eliminate the temporal redundancy present in any video sequence and use optimized search area to reduce computational time. In this paper I have reviewed existing block based motion estimation algorithms like exhaustive full search (FS), three step search (TSS), adaptive dual cross diamond hexagon search (ADCDHS) and performed a comparative analysis of their performance. I have also proposed a Modified Diamond Hexagon Search which will use reduced search area compare to existing TSS, DAHSA, and ADCDHS and in turn it will reduce computational time. Application of proposed algorithm for local motion analysis is also discussed 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.
