| Abstract | The development of positron emission tomography / computed tomography (PET / CT) has shown great success in improving the accuracy of clinic diagnosis of lung cancers. However, it is still difficult to differentiate between some normal tissues with high standard uptake value (such as inflammations) and lung tumors by general methods. The objective of this paper was to identify textural features useful in distinguishing tumor from normal tissue in PET/CT images. A computer aided diagnosis system is developed. Tumors and normal tissues were segmented by optical threshold method. Texture features were computed from every segmented regions of interest (ROI), and then analyzed according to classification of ROIs. Finally, the effectiveness of distinguishing tumor and normal tissue of every feature was compared and analyzed using distance and KNN classifier. The clinic use of the system has potential to improve in the accuracy of discriminating benign and malignant lesions. |

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.
