Local sparsity enhanced compressed sensing magnetic resonance imaging in uniform discrete curvelet domain
BACKGROUND: Compressed sensing(CS) has been well applied to speed up imaging by exploring image sparsity over predefined basis functions or learnt dictionary. Firstly, the sparse representation is generally obtained in a single transform domain by using wavelet-like methods, which cannot produce opt...
