Lanczos, everything you didn’t want to know about filtering

So spent a rather interesting day actually researching sinc algorithms. It’s all about scaling. Actually it’s all about signal processing, converting a low frequency sample into a higher one. Image processing, hours of fun, almost nine hours of fun actually. Settled on Lanczos6.

Spring is definitely here. Went for a run this evening, was supposed to be in London, but never happened. Oh it’s mother’s birthday, yep she made it through another year, never mind.
