| Abstract | In recent years, airport runway extraction has become increasingly important for various engineering applications. Existing approaches for airport runway extraction primarily focus on locating the airport roughly, i.e., determining whether an airport is present or not, but not delineating the airport runway accurately. This study develops a novel method for semiautomatic airport runway extraction from Google earth images by integrating a long straight line finder and a region-based level set evolution (LSE). Specifically, we start by detecting the long straight lines that most likely represent airport runway boundaries in the original images. Then, based on the extracted lines, we propose a method for semiautomatic generation of initial level curves for the LSE. Furthermore, for accurate extraction of the entire airport runways, a fast region-based LSE is used to evolve the initial level curves toward the desired boundaries. Experiments validate that the proposed method is capable of semiautomatically extracting objects with complex geometrical shapes and topological structures from challenging backgrounds. Compared with other state-of-the-art approaches, the proposed method has much fewer parameters and is more computationally efficient while achieving object extraction accuracy comparable to other approaches. |

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.
