public void Calc(
	IplImage image,
	bool accumulate,
	CvArr mask
)

Public Sub Calc ( 
	image As IplImage,
	accumulate As Boolean,
	mask As CvArr
)

public:
void Calc(
	IplImage^ image, 
	bool accumulate, 
	CvArr^ mask
)

member Calc : 
        image : IplImage * 
        accumulate : bool * 
        mask : CvArr -> unit

Parameters

image: Type: OpenCvSharpIplImage
Source image.
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.
