Effective Volumetric Feature Modeling and Coarse Correspondence via Improved 3DSIFT and Spectral Matching
Table 1
Mean of Square Difference on 3 real volume image pairs. SE_ represents a volume image pair, that is, SE_ is the fixed image and SE_ the moving image. The volume images are from different respiratory periods of the same person. Note that this error is small; for example, out of the gray value range of 255, indicates a mean gray difference of only 5.66.
