The Daala project is a royalty-free video codec that attempts to compete with the best patent-encumbered
codecs. Part of our strategy is to replace core tools of traditional video codecs with alternative approaches,
many of them designed to take perceptual aspects into account, rather than optimizing for simple metrics like
PSNR. This paper documents some of our experiences with these tools, which ones worked and which did not.
We evaluate which tools are easy to integrate into a more traditional codec design, and show results in the
context of the codec being developed by the Alliance for Open Media.

Conference Presentations are recordings of oral presentations given at SPIE conferences and published as part of the conference proceedings. They include the speaker's narration along with a video recording of the presentation slides and animations. Many conference presentations also include full-text papers.
