Today, Google introduced their super-resolution technology based on machine learning, RAISR:

Maybe at some point we will see an implementation that could be useful for our case.
Well, you need a huge data base of images, and a super fast search engine to match your low resolution image features to the high resolution image features in your data base. You then average the best results, and voila, there’s your high resolution image. The method is actually pretty similar to the method applied by Mike Verta, to enhance the detail of Legacy, minus the upscaling.
Dre. Did anything ever come from this? Or was it too time consuming, among other things?
