| Abstract | Considering defects of hot rolled strips are hard to be recognized by human eyes under high speed and strong noise disturbance circumstances, automatic recognition technique is discussed, and traditional space-domain feature set is very hard to be extracted, spectrum images of defects are researched in depth and are firstly extracted three types of features including Crisscross Region Feature Set which contains 240 origin features, Sum of Valid Pixels (SVP) and Repletion Ratio of Centre Region (RRCR), secondly optimized the feature set by genetic algorithm to get a bran-new feature set including 54 features. Based on the bran-new feature set, several recognition experiments of neural network are implemented, and the results show that the recognition effects under this new feature set can meet the demands of surface defect recognition of hot rolled strips in real- world under hard circumstances. Meanwhile research orientation of surface defect recognition of hot rolled strips is pointed out in order to improve recognition effects. |

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.
