GM CBF maps (middle slice) estimated using different correction methods under different noise levels. From left to right: no correction, LR, sEM, and sEM-LR methods. From top to bottom: different levels of Gaussian noise, with a standard deviation of 5, 10 and 15, respectively. The dotted box areas of ground truth and the corrected results with LR, sEM and sEM-LR were magnified into view
