| Abstract | Human eyes have limited perception capabilities; for example, only 2 degrees of our 140 degree vision field provide the highest quality of perception. Due to this fact the idea of perceptual focus emerged to allow a visual content to be changed in a way that only part of the visual field where a human gaze is directed is encoded with a high quality. The image quality in the periphery can be reduced without a viewer noticing it. This compression approach allows a significant decrease in the number of bits required for image encoding, and in the case of the 3D image rendering, it decreases the computational burden. A number of previous researchers have investigated the topic of perceptual focus but only for a single viewer. In our research we investigate a dynamically changing multi-viewer scenario. In this type of scenario a number of people are watching the same visual content at the same time. Each person has his/her own perceptual focus area which changes over time. The visual content is sent through a network with a fixed delay/lag which provides an additional challenge to the whole scheme. The goal of our work was to investigate and develop a method of multi-viewer perceptual focus zones adaptation for real-time media perceptual compression and transmission. In our research we also look into the impact that such a method can have on transmission bandwidth and computational burden reduction. |

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.
