Figure 2. — Quality of the reconstructions of the spectrum from Figure 1. (Left) The comparison of the performance of various algorithms: LPMP (solid line), iterative soft thresholding (IST) (dashed line), stage-wise orthogonal matching pursuit (StOMP) (dotted line), compressive sampling matching (COSAMP) (stared line) and orthogonal matching pursuit (OMP) (squared line). (Right) The performance of the masked LPMP algorithm (solid line) compared with the performance of non-masked LPMP algorithm (dashed line). The absolute recovery errors (in intensity units) are plotted vs. the number of sampling points.
