| Abstract | A method for improving the watermark extraction performance of the digital watermarking based on the modification of image pixels is proposed in this paper. By embedding the watermark in the chrominance channel and using the Weiner filter with 3x3 window size in the watermark extraction process, the accuracy of the extracted watermark can be improved. Sets of experiment are carried out to prove our proposed concept. The results obtained show that the improved performance in term of NC, compared to the previous method in [7], is achieved by using our proposed watermarking method. The improved robustness of the proposed method against various common imaging processing based attacks is also presented and discussed. |

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.
