Correction of radial distortion based on line-fitting

Abstract This paper presents an algorithm for correcting the distortion of a wide-angle lens with a single image. The radial distortion that transforms the horizontal and vertical lines in the real world into general curves in an image provides us with an image of degradation. Based on the principle that straight lines in the real world look straight in an image under the pinhole camera model, the proposed distortion correction algorithm extracts curves automatically and manually, fits lines to the curves, and determine the optimum distortion parameters by exploiting the Levenberg-Marquardt algorithm (LMA). Ultimately, the distortion parameters convert distorted images into undistorted ones without degradation of image quality.

About National Digital Library of India (NDLI)
NDLI logo

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.
