WebThen the described normalization: x ′ = x / S ( x) So S ( x ′) = ∑ i x i ′ = ∑ i x i S ( x) = 1 S ( x) ∑ i x i = 1 S ( x) S ( x) = 1 OK, the normalized vector x ′ has unit sum. (Beware: if S ( x) was zero, you are in for a surprise) Why doesn't it work when you subtract them from 1? http://www.ichacha.net/normalized%20value.html

Web3.1 Volumetric differences. Probably the most intuitive volumetric distance measure is the energy of the difference image a.k.a. the sum of squared differences (SSD), for a pair of mono-modality images. The underlying idea is that if image intensities match, i.e., T ( y ( x )) ≈ R ( x ), then the images correspond.
