This work proposes to employ elastic-net for MRI
reconstruction. The elastic net favours grouping effect
among the stree-structured wavelet coefficients and
thereby yields better reconstruction than straighforward
sparse reconstruction. We propose generalization of the
standard elastic net formulation by introducing an
analysis prior elastic net. The results from our
generalization yields better results than
state-of-the-art techniques in MRI reconstruction.
