Abstract :
We consider lossy compression of image sequences using lscr1 compression with over complete dictionaries. As a fidelity measure for the reconstruction quality, we incorporate the proposed structural similarity index measure, and we show that this leads to problem formulations that are very similar to conventional lscr1 compression algorithms. In addition, we develop efficient large-scale algorithms used for joint encoding of multiple image frames.
