A Bayesian wavelet-based multidimensional deconvolution with sub-band emphasis.
This paper 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 l(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.
