WebMay 1, 2024 · The basic concept that I have finalized is to split the jobs of detecting long edges, "everyday" edges and micro-aliasing into separate passes - however, for performance reasons, long edge and "everyday" edge were reasonably compatible to do in a single SMAA run. WebMar 29, 2024 · The problem with aliasing is that it cannot be distinguished between the real low resolution frequencies. But in super resolution you can make multiple low resolution measurements with aliasing and calculate the shift between the signals (afaik) that can help to reconstruct a higher resolution signal.
