Simulated Data 2D Gaussian fits at different noise levels: Fit parameters for uniform and non-uniform undersampling are shown for CS and GIRAF reconstruction. 100 experiments per noise realization were performed. Mean and standard deviation of the fit results are plotted. CS parameters degrade rapidly with increasing acceleration whereas the degradation of GIRAF fits is remarkably less. Note that the non-uniform setting performs better than uniform setting.
