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