Abstract

In this paper, we propose a rate adaptive compressed sensing for block-based DCVS framework, in which the sampling rate is estimated at the decoder side and can be sent back to the encoder via the return channel. The assignment of measurements rate (MR) is depending on the variance of the residual measurements between SI and the reconstructed CS frame. By comparing with the encoder-based scheme, the proposed scheme can achieve a comparable result with more stable and smaller transmission rate, which can briefly increase the transform efficiency as well as reduce the band width.

Keywords: adaptive compressed sensing； side information； residual variance； multihypothesis prediction
