Anti-ringing for Lanczos?

Anti-ringing for Lanczos?

Postby Vadel » Mon Sep 15, 2014 2:14 pm

I've noticed ringing when using Lanczos to scale images to screen width. There's a video renderer called madVR which uses Lanczos (as well as other algorithms) and gives the option to apply an anti-ringing filter. I wonder if it is possible to implement something like this on CDisplayEx.

This is a link where the author of madVR proposes the anti-ringing filter he uses to developers of other application: http://forum.doom9.org/showthread.php?t=145358
