FastLineDetectorDetect Method (InputArray)

Finds lines in the input image. This is the output of the default parameters of the algorithm on the above shown image.

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

Syntax

public virtual Vec4f[] Detect(
	InputArray image
)

Public Overridable Function Detect ( 
	image As InputArray
) As Vec4f()

public:
virtual array<Vec4f>^ Detect(
	InputArray^ image
)

abstract Detect : 
        image : InputArray -> Vec4f[] 
override Detect : 
        image : InputArray -> Vec4f[]

Parameters

image: Type: OpenCvSharpInputArray
A grayscale (CV_8UC1) input image. If only a roi needs to be selected, use: `fld_ptr-\>detect(image(roi), lines, ...); lines += Scalar(roi.x, roi.y, roi.x, roi.y);`

Return Value

Type: Vec4f
A vector of Vec4f elements specifying the beginning and ending point of a line. Where Vec4f is (x1, y1, x2, y2), point 1 is the start, point 2 - end.Returned lines are directed so that the brighter side is on their left.
