Interactive Multigrid Refinement for Deformable Image Registration
Figure 4
Registration results of manual revision of affine, FFD, and Demons for two clinical prostate images, respectively. (a) Affine, (b) FFD and (c) Demons. The value of SSD shows the performance of registration in overlapping areas. Generally, the lower the SSD, the better the registration results. Note that the SSD for Demons only calculates the areas of overlapping between two images.
