Answer to: What is free available libraries, packages or sdks out their to take 10m resolution imagery from sentinel 2 down to 5m resolution

With sufficiently good signal to noise and iff you know the point spread function of the imaging system very accurately then a super resolution of about 2-3x is theoretically possible with good data. The snag is that it requires an insane amount of computing power to deliver that additional resolution and the resulting image will have artefacts introduced by such aggressive post processing. That sort of deconvolution code dates back to the early HST era when the thing was hopelessly myopic with severe spherical aberration and everything had to be deconvolved to make any sense of it. The actual resolution of the reconstructed image varies with local signal to noise and artefacts can be obtrusive so you have to decide how far you are prepared to push it. In other words there is no free lunch. The zooming in sequence in Bladerunner is simply not possible! (at least not in this universe) It works a lot better for bright stars on a mostly black background where the positivity constraint on images works very effectively. It is notoriously difficult to do it on a bright object with fine dark detail. In either case it is an ill posed deconvolution problem and you have to apply some heuristic regularisation or AI to sort the wheat from the chaff. Maximum entropy is one such non-linear technique that can do this at a computational price. AI has a nasty tendency to hallucinate. Take your pick.
