Joint sparsity property of multi-contrast image coefficients. Group sparsity for traditional wavelet transform is shown in (A), (a1-a4) are images of two contrasts (T1W and T2W MRI images) and their corresponding coefficients in the 3rd sub-bands of traditional redundant Haar wavelet transform. Group sparsity of GBRWT is shown in (B) and (b1-b2) are two selected fragments of GBRWT coefficients
