CS-MRI algorithm comparison over vertebrae image (bold means the best).

	MAE	MSE	PSNR	Time (s)
ISTA [11]	1.43	7.16	39.58	9.57
SISTA [12]	1.37	5.91	40.42	7.19
FISTA [13]	1.38	6.22	40.19	7.40
FCSA [16]	1.49	8.38	38.90	5.17
EWISTARS (proposed)	1.30	4.92	41.21	7.68

PSNR is in unit of dB and time is in unit of second.
