| Abstract | A novel approach is proposed for tracking occluded vehicles in real road traffic environment. The third-level DWT is inducted into background difference to filter the high frequency noises in the background, decrease the resolution of frame and detect motion regions. A scene model and a box adjustment model are built to help predict and interpret the occlusion and tracking procedure. A 2-dimensional bounding box is used to represent vehicle, Kalman filter and weighted scale parameter to predict whose center position and motion. The final predictive vehicle-region is estimated using partial observations and adjusting unobservable bounding edges. The center of this new vehicle-region will be feedback to the Kalman filter as the measurement to modify the Kalman gain and estimate the optimum position. The proposed method is an efficient tracking algorithm, as shown in some experiments with real traffic scenes. |

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.
