[Bf-committers] [GSoC] Cycles Denoiser

[Fabrizio Destro]

Hello everybody! I am Fabrizio I always wanted to contribute to an
Open Source project. I found out about GSoC about three years ago, but
I have never applied because I wouldn't have had the time. But, this
year I would like to try.

I have looked through the proposed ideas and some of them catch my
attention. In particularly the Cycles denoiser, I have some questions
about it.

First, I want to be sure I understand what the goal is. So, the
objective is to create a node which, once the rendering is done, will
work only on the image with the goal to reduce the noise.

I am not sure about this sentence I found on the wiki: "[...] and
requires a special buffer with 'delta' information for speed, UV
[...]". This means that this node will store some data to speed up the
process on the next rendering? and if so, these data will be valid
only if the scene didn't change from the last time, right?

I am currently doing some research online and I found this publication
on the subject http://dl.acm.org/citation.cfm?doid=2776880.2792740 .
Does someone have any reference which can be useful? or maybe an idea
on some algorithms/researches?
