RAISR: Rapid and Accurate Image Super Resolution [article]

Yaniv Romano, John Isidoro, Peyman Milanfar
2016 arXiv   pre-print
Given an image, we wish to produce an image of larger size with significantly more pixels and higher image quality. This is generally known as the Single Image Super-Resolution (SISR) problem.  ...  The idea is that with sufficient training data (corresponding pairs of low and high resolution images) we can learn set of filters (i.e. a mapping) that when applied to given image that is not in the training  ...  CONCLUSION In this paper we proposed a rapid and accurate learning-based approach for single image super-resolution (called RAISR).  ...
