| Abstract | An ego-motion detection system has been developed, where edge features are extracted from an image and analyzed to detect any motion from the camera holder instead of using the conventional method of comparing pixel intensities. Such edge-based feature representation scheme reduces the computational complexity and increases the accuracy, thus being better suited to hardware implementation due to its simplicity. In this paper we have enhanced the reliability and flexibility of the system by introducing a new pre-processing scheme in edge detection and an automatic speed adaptation capability in local motion detection. The pre-processing improves the local motion detection accuracy by only highlighting the apparent general contour edges, while filtering out insignificant features in the background which may lead to misjudgement. The automatic speed adaptation capability improves the system and renders it more flexible to accommodate to more complex motion patterns with variable speeds. The system performance has been demonstrated by simulation experiments and the robustness against disturbing moving objects in the scene has also been shown. |

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.
