We proposes a new algorithm for wavelet-based multidimensional image deconvolution which employs subband-dependent minimization and the dual-tree complex wavelet transform in an iterative Bayesian framework.

In addition, this algorithm employs a new prior instead of the popular $\ell_1$ norm, and is thus able to embed a learning scheme during the iteration which helps it to achieve better deconvolution results and faster convergence.
