|Abstract||Computer vision techniques have been applied for rapid and accurate structure recovery in many fields. Most methods perform poorly in areas containing little or no texture and in the presence of repetitive patterns. We present a portable, cost-effective pattern projector system powered by the flash of a camera, to aid the reconstruction of such areas. No calibration is required between the camera-projector, projector-scene, or pattern. We demonstrate the effectiveness of our system on various representative surfaces like stone, metal, clay, porcelain, and natural fibers, with different inherent colors/textures. A pipeline is presented to automatically generate textured, true-scale metric models, that can be used for quantitative studies or visualization. The practicability of our system is explored in the specific area of digital archiving of historically significant objects. We show results from field trips to 12th century temples at Belur and Halebidu in South India and objects from the Wintherthur museum, Delaware, USA.|

Ministry of Human Resource Development (MHRD) under its National Mission on Education through Information and Communication Technology (NMEICT) has initiated the National Digital Library of India (NDLI) project to develop a framework of virtual repository of learning resources with a single-window search facility. Filtered and federated searching is employed to facilitate focused searching so that learners can find out the right resource with least effort and in minimum time. NDLI is designed to hold content of any language and provides interface support for leading vernacular languages, (currently Hindi, Bengali and several other languages are available). It is designed 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 being developed to help students to prepare for entrance and competitive examinations, 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 being developed at 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 Human Resource Development (MHRD), through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
