Intra-Paint: A new Daala demo from Jean-Marc Valin

[xiphmont]

Intra paint is not a technique that's part of the original Daala plan and, as of right now, we're not currently using it in Daala. Jean-Marc envisioned it as a simpler, potentially more effective replacement for intra-prediction. That didn't quite work out-- but it has useful and visually pleasing qualities that, of all things, make it an interesting postprocessing filter, especially for deringing.

Several people have said 'that should be an Instagram filter!' I'm sure Facebook could shake a few million loose for us to make that happen ;-)

if I remember correctly, Ghost does the opposite -- it extracts tonal signal.

Which seems the right way to me. Noise doesn't need accuracy, unlike tonal signals...
