Cv2FAST Method (InputArray, Int32, Boolean)

Detects corners using the FAST algorithm

Namespace: OpenCvSharp
Assembly: OpenCvSharp (in OpenCvSharp.dll) Version: 1.0.0

Syntax

public static KeyPoint[] FAST(
	InputArray image,
	int threshold,
	bool nonmaxSupression = true
)

Public Shared Function FAST ( 
	image As InputArray,
	threshold As Integer,
	Optional nonmaxSupression As Boolean = true
) As KeyPoint()

public:
static array<KeyPoint>^ FAST(
	InputArray^ image, 
	int threshold, 
	bool nonmaxSupression = true
)

static member FAST : 
        image : InputArray * 
        threshold : int * 
        ?nonmaxSupression : bool 
(* Defaults:
        let _nonmaxSupression = defaultArg nonmaxSupression true
*)
-> KeyPoint[]

Parameters

image: Type: OpenCvSharpInputArray
grayscale image where keypoints (corners) are detected.
threshold: Type: SystemInt32
threshold on difference between intensity of the central pixel and pixels of a circle around this pixel.
nonmaxSupression (Optional): Type: SystemBoolean
if true, non-maximum suppression is applied to detected corners (keypoints).

Return Value

Type: KeyPoint
keypoints detected on the image.
