Abstract | In large-scale video database, lots of different videos frequently share the similar content copied from the same source. Generally, those videos have certain semantic correlations, such as being of similar events and sharing the same topic. Mining these semantic correlations can greatly facilitate video search. However, as a preprocessing step, detecting and localizing the copy pair among videos, i.e. copy detection problem, plays a key role for precise semantic mining. To meet the requirements in semantic mining scenario, we propose a frame fusion based copy detection scheme. In this scheme, the copy detection problem is converted to HMM decoding problem with three relaxed constraints, where Viterbi algorithm is employed to automatically detect the copy pair. The experimental results show that the proposed approach achieves high localization accuracy even when the copied clip undergoes some complex transformations, while achieving comparable performance compared with state-of-the-art copy detection methods. |

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.
