Namespace: Emgu.CV
Assembly: Emgu.CV.World (in Emgu.CV.World.dll) Version: 4.1.1.3497 (4.1.1.3497)

Syntax

public Image<Gray, byte> Canny(
	double thresh,
	double threshLinking,
	int apertureSize,
	bool l2Gradient
)

Public Function Canny ( 
	thresh As Double,
	threshLinking As Double,
	apertureSize As Integer,
	l2Gradient As Boolean
) As Image(Of Gray, Byte)

public:
Image<Gray, unsigned char>^ Canny(
	double thresh, 
	double threshLinking, 
	int apertureSize, 
	bool l2Gradient
)

member Canny : 
        thresh : float * 
        threshLinking : float * 
        apertureSize : int * 
        l2Gradient : bool -> Image<Gray, byte>

Parameters

thresh: Type: SystemDouble
The threshhold to find initial segments of strong edges
threshLinking: Type: SystemDouble
The threshold used for edge Linking
apertureSize: Type: SystemInt32
The aperture size, use 3 for default
l2Gradient: Type: SystemBoolean
a flag, indicating whether a more accurate norm should be used to calculate the image gradient magnitude ( L2gradient=true ), or whether the default norm is enough ( L2gradient=false ).

Return Value

Type: ImageGray, Byte
The edges found by the Canny edge detector
