Cv2GaussianBlur Method OpenCvSharp Class Library
Blurs an image using a Gaussian filter.

Namespace:  OpenCvSharp.CPlusPlus
Assembly:  OpenCvSharp.CPlusPlus (in OpenCvSharp.CPlusPlus.dll) Version: 1.0.0.0 (1.0.0.0)
Syntax

public static void GaussianBlur(
	InputArray src,
	OutputArray dst,
	Size ksize,
	double sigmaX,
	double sigmaY = 0,
	BorderType borderType = BorderType.Reflect101
)

Parameters

src
Type: OpenCvSharp.CPlusPlusInputArray
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.
dst
Type: OpenCvSharp.CPlusPlusOutputArray
output image of the same size and type as src.
ksize
Type: OpenCvSharp.CPlusPlusSize
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* .
sigmaX
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: OpenCvSharpBorderType
pixel extrapolation method
