Discussion
The function iplCentralMoment() computes the central moment U
U
(m,n)
for the image .
NormalizedSpatialMoment
Computes a normalized
spatial moment.
double iplNormalizedSpatialMoment(IplImage* image , int
mOrd , int nOrd );
image The image for which the moment will be
computed.
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.

Here M
U
(m,n) is the spatial moment, nCols and nRows are the numbers of
pixel columns and rows, respectively.
