| Abstract | This paper presents a simple and effective method to automatically evaluate the cut grade for small round diamond. The prerequisite to conduct the method is the accurate edge extraction of diamond table facet. A two-stage approach is developed in this paper to extract the table edge of diamond, by conducting a counting process for rough estimation, followed by modified virtual motion. With the accurate edge extraction result, the cut grade of diamond can be successfully evaluated. The experimental results show that the proposed method can accurately evaluate the cut grade of diamond and the overall performance meets the requirement of cut grading standards. |

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.
