Fig. 13From: Joint sparse reconstruction of multi-contrast MRI images with graph based redundant wavelet transformReconstructed error (× 5) using 2D Random under-sampling, with 15% sampled data in Fig. 7(a1-a2), and 26% sampled data in Fig. 7(b1-b4). Rows 1–6 are reconstruction errors correspond to multi-contrast images shown in Figs. 7(a1-a2, b1-b4) respectively. Columns 1–4 denote the results obtained from GBRWT, JSIDWT, JBCS and JGBRWT respectivelyBack to article page
