Cv2GpuLaplacian Method OpenCvSharp Class Library
Applies the Laplacian operator to an image.

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

public static void Laplacian(
	GpuMat src,
	GpuMat dst,
	int ddepth,
	int ksize = 1,
	double scale = 1,
	BorderType borderType = BorderType.Reflect101,
	Stream stream = null
)

Parameters

src
Type: OpenCvSharp.CPlusPlus.GpuGpuMat
Source image. CV_8UC1 and CV_8UC4 source types are supported.
dst
Type: OpenCvSharp.CPlusPlus.GpuGpuMat
Destination image. The size and number of channels is the same as src.
ddepth
Type: SystemInt32
Desired depth of the destination image. It supports only the same depth as the source image depth.
ksize (Optional)
Type: SystemInt32
Aperture size used to compute the second-derivative filters. It must be positive and odd. Only ksize = 1 and ksize = 3 are supported.
scale (Optional)
Type: SystemDouble
Optional scale factor for the computed Laplacian values.
borderType (Optional)
Type: OpenCvSharpBorderType
Pixel extrapolation method.
stream (Optional)
Type: OpenCvSharp.CPlusPlus.GpuStream
Stream for the asynchronous version.
