| Abstract | In Wyner–Ziv (WZ) video coding, side information (SI), which is a decoder estimation of the original frame, plays a key role in overall compression performance. Many researchers have focused on SI in the past decade to develop efficient SI generation algorithms. In this study, the authors propose an algorithm combined with naive Bayesian theory to create a generic model that can complete the generation of SI in the WZ video coding framework. The proposed scheme first utilises samples to build the initial model, after which the algorithm filters the samples and models according to the threshold T 1 . Then, the algorithm takes the filtered samples and models as conditions to build the generic model. Finally, the proposed scheme completes the generation of SI with the motion vectors obtained from the generated model. Experimental results show that the proposed algorithm achieves better rate-distortion performance and improves peak signal-to-noise ratio by up to 0.5 and 2 dB compared with state-of-the-art techniques. |

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.
