| Abstract | Based on the Lucas-Kanade optical flow method, a dynamically selecting model is proposed in this paper to track a moving object. This model is composed of an object model, a consistency constraint model, and a random sampling model. Based on the current image frame, the object model is used to calculate the relevant feature points for the next frame. The random sampling model is used to resample the feature points from the current frame and the relevant points on the next frame. By considering the consistency constraints in speed, direction and the object stability, the consistency constraint model is used to check the consistency for the feature points obtained by the object model, remove some unfit feature points, and add some new feature points obtained by the random sampling model. A stable tracking trajectory would be obtained during the tracking process using the proposed method. Simulation experiments comparing with traditional methods are conducted in different situations, such as illumination change, partial occlusion, high-speed motion, and object image with noise. The results show that the proposed object tracking method has better performance, which includes partial non-rigid object and varying velocity running object in real-time environment with robustness. |

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.
