Is this work been already used in emulators filters?

  Filters have achcieved similar results, but not quite with the same technique! Or, this algorithm wasn’t intended for real-time processing and creates an adjacency graph of similar pixels. Once it’s done that, it will try to fit/optimize splines over the regions. Emulator filters like hqx determine each pixel’s “upscaled shape” by the colours of its neighbours, usually indexed with a table.
