| Abstract | This paper presents a system to automatically analyse a basketball long-shot using trajectory-based ball tracking method from a basketball video sequence. The accuracy of a long-shot in a basketball game is mostly dependent on the ball throwing angle and the velocity at which the ball is to be thrown. The proposed system detects and tracks the ball in a basketball long-shot sequence by exploiting the trajectory information of the ball. The ball motion characteristics are used to determine the ball trajectory. The candidate trajectories are generated from a set of ball candidates in each frame. The trajectory-based ball tracking minimised the rate of error of ball tracking in the video which occurs due to occlusion and merging of the ball image with other objects in the frame, distortion of the ball image due to ball and camera motion and the presence of many moving objects in the foreground and background in the video. The ball locations verified by the tracking results are then used to estimate the ball throwing angle and the throwing velocity. The experiments show encouraging results for videos with dynamic background and different illumination conditions. |

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.
