Eigenimages Interpretation
Eigenimages Interpretation
Yet another way of looking at what is being said if some Sm,
say S1, is much larger than any of the other Sm can be seen if we
rewrite the equation as:
If all other Sm are small, the summation term becomes
negligible and
can be ignored (but to the extent any of the (Pm*)
aren’t small relative to the associated (P1*) for some of
the eigenimages, they can’t be ignored … note this may
come into play for any scan where nT1 is almost zero, even if
(S1E1*) is relatively large).
