Parameters
- pState
- Pointer to the structure that stores image moments.
- mOrd, nOrd
- Integer power exponents defining the moment order. These arguments must satisfy the condition 0≤mOrd+nOrd≤3.
- nChannel
- The channel for which the moment is returned.
- roiOffset
- Offset in pixels of the ROI origin (top left corner) from the image origin.
- pValue
- Pointer to the retrieved moment value.
Description
This function returns the pointer
pValue
to the spatial moment that was previously computed by the ippiMoments function. All spatial moment values are computed by ippiMoments relative to the image ROI origin. You may also obtain spatial moment values relative to different point in the image, using the appropriate roiOffset
settings.The moment order is specified by the integer exponents
mOrd, nOrd.
Return Values
- ippStsNoErr
- Indicates no error. Any other value indicates an error or a warning.
- ippStsNullPtrErr
- Indicates an error condition ifpStateorpValuepointer isNULL.
- ippStsContextMatchErr
- Indicates an error condition if a pointer to an invalid structure is passed.
- ippStsSizeErr
- Indicates an error condition ifmOrd + nOrdis greater than 3, ornChannelhas an illegal value.
