Beschreibung:
With the explosion of Internet technology and graphics engines, digital images are now everywhere. Image capturing tools are all pervading - in our pockets to inside a satellite. And although imaging applications demand an availability to high resolution images, such images are not picture perfect and may be lacking sufficient details. This requires that these images be super-resolved for improved details. How to achieve this is what constitutes research in the area of image super-resolution.
This book explains the state-of-the-art techniques used to create extremely high-resolution, or super-resolution (SR) images, from a set of low-resolution images. The current literature in this topic deals primarily with the use of motion cues for the purpose of generating SR images. These cues have, it is shown, their advantages and disadvantages. In contrast, this book shows that cues other than motion can also be used for the same purpose, and addresses both the merits and demerits of such new techniques as defocus, photometric, wavelet-based, and zoom cues.
Research on Image Super-Resolution.- Use of Defocus Cue.- Photometry Based Method.- Blind Restoration of Photometric Observations.- Use of Learnt Wavelet Coefficients.- Extension of Generalized Interpolation to Eigen Decomposition.- Use of Zoom Cue.- Looking Ahead.
