Deblurring results of$\mathbf{64}\mathbf{\times }\mathbf{80}$part of sparse Word image convolved by a$\mathbf{3}\mathbf{\times }\mathbf{5}$motion kernel generated by the MATLAB command$\mathbf{fspecial}\mathbf{(}\mathbf{\text{‘}}\mathbf{motion}\mathbf{\text{’}}\mathbf{,}\mathbf{5}\mathbf{,}\mathbf{7}\mathbf{)}$. Upper left: original image; upper middle: blurred image. The other four are reconstructed images, respectively, by the $A^T$ Bregman iteration, the reweighted ${\ell }_1$ minimization algorithm, the $A^{†}$ Bregman iteration, and the chaotic iteration.
