NormalizedCentralMoment
Computes a normalized
central moment.
double iplNormalizedCentralMoment(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.
Discussion
The function iplNormalizedCentralMoment() computes the normalized
central moment U
U
(m,n)/( nCols
m
· nRows
n
) for the image .
Here U
U
(m,n) is the central moment, nCols and nRows are the numbers of
pixel columns and rows, respectively.
