We consider source requantization in two forms -- successive degradation (i.e., source fidelity reduction) and bit stealing (i.e., information embedding) -when no forward planning...

In this paper we propose an algorithm for image recovery where completely lost blocks in an image/video-frame are recovered using spatial information surrounding these blocks. Our...
