Sparse-Representation-Based Direct Minimum L (p)-Norm Algorithm for MRI Phase Unwrapping
A sparse-representation-based direct minimum L (p)-norm algorithm is proposed for a two-dimensional MRI phase unwrapping. First, the algorithm converts the weighted-L (p)-norm-minimization-based phase unwrapping problem into a linear system problem whose system (coefficient) matrix is a large, symme...
