| Abstract | In this paper, we present a novel Expectation Maximization (EM) algorithm for automatic color image inpainting using a new discrete multi scale directional sparse representation called the Discrete Shearlet Transform (DST). It is now acknowledged that the traditional wavelets are not very effective when dealing the multi dimensional signals having distributed discontinuities such as edges. To achieve a more efficient representation one has to use basis elements with much higher directional sensitivity. Using a Shearlet Transform combines the power of multi scale methods with a unique ability to capture the geometry of multidimensional data and is optimally efficient in representing images with edges. The inpainting can be viewed as an interpolation or estimation problem with missing data. Towards this goal, we propose the idea of using Expectation Maximization (EM) algorithm in a Bayesian Framework, which is used to recover the missing samples using a sparse representation-Discrete Shearlet Transform (DST). We first introduce an easy and efficient sparse representation-Discrete Shearlet Transform (DST) based iterative algorithm for image inpainting. And then, we derive its convergence properties. We can demonstrate that this algorithm based on a new sparse representation-Discrete Shearlet Transform is very competitive in image inpainting applications both in terms of performance and computational efficiency. |

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.
