| Abstract | Non-rigid registration of lung computed tomography (CT) images is a valuable tool for various clinical applications. Many methods such as bilateral filters and census transform have been used to deal with discontinuity of lung motion and local intensity variation. However, census transform cannot distinguish between low and high contrast regions, which may lead to negative influence to differential-based registration methods. A novel distinctive local binary pattern that can generate distinctive representations of high contrast images is proposed. Combing the novel local binary pattern, bilateral filters, the inverse-consistent symmetrical method and the Lucas–Kanade method, a novel accurate image registration method is developed. The experiments are performed on the publicly available 4D CT lung dataset from DIR-Lab. Compared with the census transform, the proposed distinctive local binary pattern can achieve relatively better results. The proposed image registration method greatly improves the accuracy of the classical Lucas–Kanade method and the bilateral filters-based Demons. In addition, the proposed registration method is most accurate among all unmasked methods tested on this dataset. |

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.
