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(
	CvArr^ arr, 
	CvHistogram^ hist, 
	bool accumulate
)

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

Parameters

arr: Type: OpenCvSharpCvArr
A Source image (though, you may pass CvMat** as well).
hist: Type: OpenCvSharpCvHistogram
Reference to the histogram.
