Description

This function operates with ROI (see Regions of Interest in Intel IPP). This function computes all spatial and central moments of order 0 to 3 for the source image

pSrc

. The seven Hu moment invariants are also computed. Different functions,

ippiMoments64s

and

ippiMoments64f,

are used to compute image moments in integer and floating-point formats, respectively.

The

ippiMoments

function computes spatial moment values relative to the image point referred to by

pSrc

. Note that this point is the ROI origin and may not coincide with the entire image origin. If you need to obtain spatial moment values relative to the actual image origin, use ippiGetSpatialMoment functions to recalculate them.

The moments' values are stored in the

pCtx

structure. To retrieve a particular moment value, use one of the functions described in the sections that follow.
