Abstract | In this work a novel scheme is proposed for adaptive early SKIP mode decision in the multiview video coding based on mode correlation in the 3D-neighborhood, variance, and ratedistortion properties. Our scheme employs an adaptive thresholding mechanism in order to react to the changing values of Quantization Parameter (QP). Experimental results demonstrate that our scheme provides a consistent time saving over a wide range of QP values. Compared to the exhaustive mode decision, our scheme provides a significant reduction in the encoding complexity (up to 77%) at the cost of a small PSNR loss (0.172 dB in average). Compared to state-of-the-art, our scheme provides an average 2× higher complexity reduction with a relatively higher PSNR value (avg. 0.2 dB). |

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.
