Beyond pure quality: Progressive modes, region of interest coding, and real time video decoding for PDE-based image compression ?
We add new features to the diffusion-based codec R-EED that go beyond pure quality. Our new progressive modes for R-EED can outperform JPEG and JPEG2000. Tree-based subdivision allows efficient region of interest coding. Diffusion-based video decoding is possible in real-time without sacrificing quality. Our newly proposed features are pairwise compatible and can be used simultaneously.
