Abstract

A new class of wavelet-type frames in signal space that uses (anti)symmetric waveforms is utilized for the development of robust error recovery algorithms for transmitted of rich multimedia content over lossy networks. That algorithms use the redundancy inherent in frame expansions. The construction employs interpolatory filters with rational transfer functions that have linear phase. Experimental results recover images when (as much as) 60% of the expansion coeeficients s are either lost or corrupted. Finally, the frame-based error recovery algorithm is compared with a classical coding approach.
