MatFilter2D Method

Convolves an image with the kernel

Namespace:  OpenCvSharp
Assembly:  OpenCvSharp (in OpenCvSharp.dll) Version: 1.0.0
Syntax
public Mat Filter2D(
	MatType ddepth,
	InputArray kernel,
	Nullable<Point> anchor = null,
	double delta = 0,
	BorderTypes borderType = BorderTypes.Reflect101
)

Parameters

ddepth
Type: OpenCvSharpMatType
The desired depth of the destination image. If it is negative, it will be the same as src.depth()
kernel
Type: OpenCvSharpInputArray
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: OpenCvSharpBorderTypes
The pixel extrapolation method

Return Value

Type: Mat
The destination image. It will have the same size and the same number of channels as src
