CvInvokeGaussianBlur Method
Blurs an image using a Gaussian filter.

Namespace: Emgu.CV
Assembly: Emgu.CV.World (in Emgu.CV.World.dll) Version: (
public static void GaussianBlur(
	IInputArray src,
	IOutputArray dst,
	Size ksize,
	double sigmaX,
	double sigmaY = 0,
	BorderType borderType = BorderType.Reflect101


Type: Emgu.CVIInputArray
input image; the image can have any number of channels, which are processed independently, but the depth should be CV_8U, CV_16U, CV_16S, CV_32F or CV_64F.
Type: Emgu.CVIOutputArray
output image of the same size and type as src.
Type: System.DrawingSize
Gaussian kernel size. ksize.width and ksize.height can differ but they both must be positive and odd. Or, they can be zero’s and then they are computed from sigma* .
Type: SystemDouble
Gaussian kernel standard deviation in X direction.
sigmaY (Optional)
Type: SystemDouble
Gaussian kernel standard deviation in Y direction; if sigmaY is zero, it is set to be equal to sigmaX, if both sigmas are zeros, they are computed from ksize.width and ksize.height , respectively (see getGaussianKernel() for details); to fully control the result regardless of possible future modifications of all this semantics, it is recommended to specify all of ksize, sigmaX, and sigmaY.
borderType (Optional)
Type: Emgu.CV.CvEnumBorderType
Pixel extrapolation method
