Encoding of predictive error frames in rate scalable video codecs using wavelet shrinkage
Eduardo Asbun, Paul Salama, Edward J. Delp · 2003
Rate scalable video compression is appealing for low bit rate applications, such as video telephony and wireless communication, where bandwidth available to an application cannot be guaranteed. In this paper, we investigate a set of strategies to increase the performance of SAMCoW, a rate scalable encoder. These techniques are based on based on wavelet decomposition, spatial orientation trees, and motion compensation.
