cvMoments Method (arr, moments, binary)
NamespacesEmgu.CVCvInvokecvMoments(IntPtr, MCvMoments%, Int32)

Calculates spatial and central moments up to the third order and writes them to moments. The moments may be used then to calculate gravity center of the shape, its area, main axises and various shape characeteristics including 7 Hu invariants.
