Distributed Video Coding (DVC),
which is a new image compression paradigm, attracts
a lot of attention from video researchers.
While computational cost of DVC encoding is lower than that of MPEG-2,
low coding efficiency has been an issue for practical DVC applications.
In this paper, a likelihood estimation method for transform domain DVC is proposed,
which uses Cauchy distribution as a virtual channel model.
In the decoder, virtual channel is estimated by utilizing error
between forward and backward predicted images for each frequency component.
Likelihood is obtained from estimated virtual channel.
Simulation results show that the proposed method can estimate the error rate with 1.6% error on average. |
