Abstract | In this paper nonlinear dimension reduction methods are applied to hyperspectral images and the segmentation performance is investigated. The biggest disadvantage of nonlinear dimension reduction techniques is their long computational processing time. To overcome this problem, prototypes which represent the spectral distribution of the scene have been obtained with vector quantization and dimension reduction has been applied on these prototypes. Dimension reduction of all pixels in the scene has been accomplished using Radial Basis Function (RBF) neural networks and the developed dasiaK-point mean interpolationpsila method. The positive effects of these methods on the segmentation of the scene have been presented in the experimental results section using objective evaluation criterion. |

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.
