| Abstract | This paper describes an automated pixel classification method using surface expansion. The originality of this work resides in the definition and use of small pictures (called "imagelet") of increasing size centered on the pixel of interest. This allows for the extraction of a set of local and global parameters associated to the pixel investigated. This set of parameters then permits body tissue separation. Classification was obtained using a multilayer artificial neural network. The new approach proposed was applied to main lower limb tissue classification in MRI image sequences. Four kinds of body tissue were taken into consideration in this study (muscle, adipose tissue, cortical bone and spongy bone). A database consisting of 1400 prototypes was created in order to evaluate this method's performances. The classification success rate was found to be 87%. This method therefore proved to be reliable and robust to analyze MRI image sequences in 20 lower limbs, representing about 2000 pictures |

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.
