Amaze has now been around for five years or so, so Adobe's engineers have certainly had a chance to evaluate what's probably the best all around demosaicing algorithm and use it as the target to beat. So why can't they come close? I'm not even talking about detail here. Adobe's algorithm gives lousy noise compared to Amaze, and Amaze isn't even an algorithm optimized for low noise (e.g. LMMSE or IGV).
