| Abstract | To resolve the problem of performance degeneration of K-S test for non-independent samples, one enhanced version of K-S test based on data per-treatment is proposed. Before K-S test, the samples are extracted with an interval which is decided by independence test in this enhanced method for ensuring independence. Considering the fact of the absence of statistical analysis about land image data of high-resolution SAR, the data of grassland is modeled by studying the data's compatibility with SIRV model. To resolve the problem that the higher order statistical characteristic is mathematically tractable in SIRV model, the definition of “Coherent Region” is proposed, which means the image is processed locally, according to the viewpoint that the texture component is slowly-varying in SIRV model. The experiments show that the enhanced method of K-S test has perfect robustness for non-independent samples. The data for the grassland here are compatible with SIRV model. By analysis of grassland data, the rationality of the concept of “Coherent Region” is proved and the space scale of “Coherent Region” for the data is found here. |

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.
