| Abstract | This paper presents single-image based super-resolution (SR) algorithm using selective frequency decomposition in the wavelet domain. We synthesize the diagonal high-frequency (HH) sub-band of the discrete wavelet transform (DWT) using the low frequency component of the low-resolution (LR) image and the high frequency component of the bi-cubic interpolated image in the HH sub-band of the DWT. The reconstructed HR image is obtained by inverse wavelet transforming the synthesized HH sub-band together with the remaining three sub-bands. The HR image is further enhanced using directional edge sharpening. The proposed single-image based SR algorithm can be used to provide digital zoom or SR functions for consumer imaging devices such as mobile phone cameras, camcorders, and surveillance cameras. Experimental results demonstrate that the proposed algorithm outperforms the existing single-image based SR algorithms in the sense of having reconstructed high-frequency components with minimum ringing artifacts. |

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.
