As a contribution to Monty's Daala demo effort, I decided to demonstrate a technique I've recently been developing for Daala: image painting. The idea is to represent images as directions and 1-D patterns.

Hi Jean-Marc!
What a pity that so many ideas the Daala team tried have not lead to some real results. I actually found some of the ideas of the Daala team very promising. But this is probably the burden of doing an original research, not just implementing known algorithms.
Nevertheless, keep on with your fascinating work!

We definitely had a few things that didn't work out, but overall we're getting better and (as you can see in the demo) clearly ahead of JPEG. In this particular case, the painting algo didn't work as an intra prediction replacement, but so far it's promising as a deringing filter.
