Copy

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

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

public:
static void CalcArrHist(
	CvArr^ arr, 
	CvHistogram^ hist, 
	bool accumulate, 
	CvArr^ mask
)

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

Parameters

arr: Type: OpenCvSharpCvArr
A Source image (though, you may pass CvMat** as well).
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.
mask: Type: OpenCvSharpCvArr
The operation mask, determines what pixels of the source images are counted.
