Type: array<System..::..IntPtr>[]()[][]
Source images (though, you may pass CvMat** as well), all are of the same size and type
Type: System..::..IntPtr
Pointer to the histogram
Type: System..::..Int32
Accumulation flag. If it is set, the histogram is not cleared in the beginning. This feature allows user to compute a single histogram from several images, or to update the histogram online
Type: System..::..IntPtr
