based on my experience with bpg compression of 39 megapixel image takes 2s with jpeg turbo (the original is a raw tiff but already cached). same image bpg is 8m30s. this is on an ivy bridge xeon. i was wanting to smash a few hundred thousand of these 39mp images for transport and backup storage but unacceptible time wise. how much faster would daala be than hvec?
- shmerl 12y agoDaala's methodology of video compression differs from HEVC, namely it optimizes the perceived quality of the image. So in theory it can be computationally lighter, because it can save on areas which are affecting perception less. But it's not there yet. Here is an overview of this idea: http://jmvalin.ca/video/spie_pvq_abstract.pdf http://jmvalin.ca/video/spie_pvq_abstract.pdf I'm not sure though how exactly it translates into still images compression efficiency. For video they do plan to eventually beat HEVC both on quality and algorithmic delay.
