Cv2Filter2D Method OpenCvSharp Class Library
Convolves an image with the kernel

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

public static void Filter2D(
	InputArray src,
	OutputArray dst,
	MatType ddepth,
	InputArray kernel,
	Nullable<Point> anchor = null,
	double delta = 0,
	BorderType borderType = BorderType.Reflect101
)

Parameters

src
Type: OpenCvSharp.CPlusPlusInputArray
The source image
dst
Type: OpenCvSharp.CPlusPlusOutputArray
The destination image. It will have the same size and the same number of channels as src
ddepth
Type: OpenCvSharp.CPlusPlusMatType
The desired depth of the destination image. If it is negative, it will be the same as src.depth()
kernel
Type: OpenCvSharp.CPlusPlusInputArray
Convolution kernel (or rather a correlation kernel), a single-channel floating point matrix. If you want to apply different kernels to different channels, split the image into separate color planes using split() and process them individually
anchor (Optional)
Type: SystemNullablePoint
The anchor of the kernel that indicates the relative position of a filtered point within the kernel. The anchor should lie within the kernel. The special default value (-1,-1) means that the anchor is at the kernel center
delta (Optional)
Type: SystemDouble
The optional value added to the filtered pixels before storing them in dst
borderType (Optional)
Type: OpenCvSharpBorderType
The pixel extrapolation method
