Figure 2From: A primal-dual fixed point algorithm for minimization of the sum of three convex separable functions Recovery results from four-channel in-vivo spine data with the subsampling ratio \(\pmb{R=2, 4}\) . For \(\pmb{\mathrm{PDFP}^{2}\mathrm{O}}\) and PDFP, \(\pmb{\lambda =1/8}\) , \(\pmb{\gamma=2}\) , and for \(\pmb{\mathrm{PDFP}^{2}\mathrm{O}_{C}}\) , \(\pmb{\lambda=1/9}\) , \(\pmb{\gamma =2}\) .
