Copy

public static void CalcHist(
	IplImage[] image,
	CvHistogram hist,
	bool accumulate,
	CvArr mask
)

Public Shared Sub CalcHist ( 
	image As IplImage(),
	hist As CvHistogram,
	accumulate As Boolean,
	mask As CvArr
)

public:
static void CalcHist(
	array<IplImage^>^ image, 
	CvHistogram^ hist, 
	bool accumulate, 
	CvArr^ mask
)

static member CalcHist : 
        image : IplImage[] * 
        hist : CvHistogram * 
        accumulate : bool * 
        mask : CvArr -> unit

Parameters

image: Type: OpenCvSharpIplImage
Source images, 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.
mask: Type: OpenCvSharpCvArr
The operation mask, determines what pixels of the source images are counted.
