| Abstract | An important area of computer vision is the detection and tracking of moving people in television images. This paper descr ibes the development of a computer vision system which can detect and track human motion across the international border between the United States and Mexico. The system consists of 16 parallel microprocessors which each operate on a segment of the total video image to determine if there has been motion in that segment of the image. Motion is detected based upon a novel scheme for calculating the median pixel value in the segment and comparing it with the median value from an earlier frame. Motion is detected if the median varies by more than a predetermined amount. When this happens a bit is sent to a controlling CPU. Also, each segment exchanges information with its neighbors thereby improving its ability to track the motion of a person. The paper also describes a practical realization of the design and problems associated with its use in a practical security system. |

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.
