Copy

public static void CalcArrHist(
	CvArr[] arr,
	CvHistogram hist,
	bool accumulate
)

Public Shared Sub CalcArrHist ( 
	arr As CvArr(),
	hist As CvHistogram,
	accumulate As Boolean
)

public:
static void CalcArrHist(
	array<CvArr^>^ arr, 
	CvHistogram^ hist, 
	bool accumulate
)

static member CalcArrHist : 
        arr : CvArr[] * 
        hist : CvHistogram * 
        accumulate : bool -> unit

Parameters

arr: Type: OpenCvSharpCvArr
Source images (though, you may pass CvMat** as well), all are of the same size and type.
hist: Type: OpenCvSharpCvHistogram
Reference to the histogram.
accumulate: Type: SystemBoolean
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.
