Parameters

src

Type: OpenCvSharp.CPlusPlus.GpuGpuMat
Source image. CV_8UC1, CV_8UC4, CV_16SC1, CV_16SC2, CV_16SC3, CV_32SC1, CV_32FC1 source types are supported.

dst

Type: OpenCvSharp.CPlusPlus.GpuGpuMat
Destination image with 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. If they are zeros, they are computed from sigma1 and sigma2 .

buf

Type: OpenCvSharp.CPlusPlus.GpuGpuMat

[Missing <param name="buf"/> documentation for "M:OpenCvSharp.CPlusPlus.Gpu.Cv2Gpu.GaussianBlur(OpenCvSharp.CPlusPlus.Gpu.GpuMat,OpenCvSharp.CPlusPlus.Gpu.GpuMat,OpenCvSharp.CPlusPlus.Size,OpenCvSharp.CPlusPlus.Gpu.GpuMat,System.Double,System.Double,OpenCvSharp.BorderType,OpenCvSharp.BorderType,OpenCvSharp.CPlusPlus.Gpu.Stream)"]

sigma1

Type: SystemDouble
Gaussian kernel standard deviation in X direction.

sigma2 (Optional)

Type: SystemDouble
Gaussian kernel standard deviation in Y direction. If sigma2 is zero, it is set to be equal to sigma1 . If they are both zeros, they are computed from ksize.Width and ksize.Height, respectively. To fully control the result regardless of possible future modification of all this semantics, you are recommended to specify all of ksize, sigma1, and sigma2.

rowBorderType (Optional)

Type: OpenCvSharpBorderType
Pixel extrapolation method in the vertical direction.

columnBorderType (Optional)

Type: OpenCvSharpBorderType
Pixel extrapolation method in the horizontal direction.

stream (Optional)

Type: OpenCvSharp.CPlusPlus.GpuStream
Stream for the asynchronous version.
