Moments
Computes all image
moments of order 0 to 3.
void iplMoments(IplImage* image , IplMomentState mState );
image The image for which the moments will be
computed.
mState The structure for storing the image moments.
Discussion
The function iplMoments() computes all spatial and central moments of
order 0 to 3 for the
image . The moments and the corresponding scaling
factors are stored in the
mState structure. To retrieve a particular moment
value, use the functions described in the sections that follow.
GetSpatialMoment
Returns a spatial moment
computed by iplMoments.
double iplGetSpatialMoment(IplMomentState mState , int
mOrd , int nOrd );
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.
