| Abstract | Color constancy is the ability to remove the dependency of illuminant and show the intrinsic color of objects. A novel multi-view video coding scheme integrated with color constancy algorithms is introduced in this paper. Color constancy algorithms based on gray-edge hypothesis are selected. The new scheme takes color constancy as a preprocessing to make the sequence independent of the illuminant conditions. Based on the examination of the scene change in the sequence, the key frames are picked out and the parameters of color constancy are determined. The illuminant information is sent into the encoder along with the illuminant independent sequence, and then it is used to solve the color cast problem of multi-view coding at the decoder. Both visual quality and coding performance prove that this novel scheme can lower the bitrates and gain better color quality. |

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.
