To my wife, Mitu - Vivek Bannore Preface Preface In many imaging systems, under-sampling and aliasing occurs frequently leading to degradation of image quality. Due to the limited number of sensors available on the digital cameras, the quality of images captured is also limited. Factors such as optical or atmospheric blur and sensor noise can also contribute further to the d- radation of image quality. Super-Resolution is an image reconstruction technique that enhances a sequence of low-resolution images or video frames by increasing the spatial resolution of the images. Each of these low-resolution images contain only incomplete scene information and are geometrically warped, aliased, and - der-sampled. Super-resolution technique intelligently fuses the incomplete scene information from several consecutive low-resolution frames to reconstruct a hi- resolution representation of the original scene. In the last decade, with the advent of new technologies in both civil and mi- tary domain, more computer vision applications are being developed with a demand for high-quality high-resolution images. In fact, the demand for high- resolution images is exponentially increasing and the camera manufacturing te- nology is unable to cope up due to cost efficiency and other practical reasons.

Virtual learning plays an important role in providing academicians, educators and students alike, with advanced learning experiences. At the forefront of these current technologies are knowledge-based systems that assess the environment in which such learning will occur and are adaptive by nature to the individual needs of the user. This monograph provides a wide range of innovative approaches of virtual education with a special emphasis on inter-disciplinary approaches. The book covers a multitude of important issues on the subject of "Innovations in Knowledge-Based Virtual Education," aiming at researchers and practitioners from academia, industry, and government. The carefully selected contributions report on research, development and real-world experiences of virtual education such as intelligent virtual teaching, web-based adaptive learning systems, intelligent agents or using multiagent intelligence.
