SpatialMoment
Computes a spatial
moment.
double iplSpatialMoment(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 iplSpatialMoment() computes the spatial moment M
U
(m,n)
for the image .
CentralMoment
Computes a central
moment.
double iplCentralMoment(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.
