| Abstract | De-speckling is an important problem in synthetic aperture radar (SAR) image analysis. Speckle noise in SAR images is assumed to be representation of a multiplicative noise. Digital images plays an significant role in daily life applications such as satellite television, images of magnetic resonance as well as in the area of study such as remote sensing applications, geographic information system. The data set which are collected by the image sensor are sometimes polluted or infected by noise. The Synthetic Aperture Radar (SAR) is very useful for providing information about earth's surface by using the relative motion between antenna and its target. However, these images are affected with granular noise termed as Speckle noise. Speckle removal is one of many cause to give efficient image visualization, thus remains a major issue in SAR image processing. To address this problem here proposed the clustering based schema along with Linear Discriminant Analysis(LDA). The denoising of SAR image is based on clustering the noisy image into several disjoint local regions which has similar spatial structure and then again denoise each splitted regions by using wiener filtering in domain Linear Discriminant Analysis(LDA). The experimental resultant shows that the denoised patches of all clusters were finally used to reconstruct the noise-free image. |

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.
