mState The structure storing the image moments.
mOrd, nOrd The integer exponents m and n (see the moment
definition in the beginning of this section).
These arguments must satisfy the condition
0
≤ mOrd + nOrd ≤ 3.
Discussion
The function iplGetNormalizedSpatialMoment() returns the
normalized spatial moment M
U
(m,n)/( nCols
m
· nRows
n
), where M
U
(m,n)is
the spatial moment previously computed by the
iplMoments() function,
nCols and nRows are the numbers of columns and rows, respectively.
GetNormalizedCentralMoment
Returns the normalized
central moment computed
by iplMoments.
