| Abstract | The brittleness of ceramic materials causes surface defect of ceramic products in the phase of manufacturing and processing. The defect on surface and subsurface will obviously decrease the fatigue life of ceramics. To improve the quality of end products, we have studied the mechanism of formation and expansion of surface defects in this paper. An improved image processing and recognition algorithm based on ANN is proposed to perform shape features extraction for the separated surface defects. By the results in experiments it is verified that: The previous 7 regularized defect boundary Fourier descriptors can better difference the defects with 10 features according to the features like wear defect area and discontinuous divided objects. We also establish and train two ANN classifiers separately corresponding to the features, whose accuracy is 97.5% in histogram feature classifier and 90.3% in shape feature classifier. |

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.
