Model-based decentralized Bayesian algorithm for distributed compressed sensing

作者:

Highlights:

• We proposed wavelet-based multi-scale model in Bayesian DCS.

• We used Bessel-K-form distribution in our algorithm, named WBDCS-BKF.

• WBDCS-WBKF uses both the tree structure and neighborhood relation of wavelet coefficients.

• VB inference procedure is used to derive posterior distributions.
