detect()

void OpenCVForUnity.XimgprocModule.FastLineDetector.detect	(	Mat	image,
		Mat	lines
	)

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

image

Parameters

image	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);
lines	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.

Dispose()

override void OpenCVForUnity.XimgprocModule.FastLineDetector.Dispose ( bool  disposing )

protectedvirtual

Reimplemented from OpenCVForUnity.CoreModule.Algorithm.

drawSegments() [1/4]

void OpenCVForUnity.XimgprocModule.FastLineDetector.drawSegments	(	Mat	image,
		Mat	lines,
		bool	draw_arrow,
		Scalar	linecolor,
		int	linethickness
	)

Draws the line segments on a given image.

Parameters

image	The image, where the lines will be drawn. Should be bigger or equal to the image, where the lines were found.
lines	A vector of the lines that needed to be drawn.
draw_arrow	If true, arrow heads will be drawn.
linecolor	Line color.
linethickness	Line thickness.

drawSegments() [2/4]

void OpenCVForUnity.XimgprocModule.FastLineDetector.drawSegments	(	Mat	image,

Parameters

image	The image, where the lines will be drawn. Should be bigger or equal to the image, where the lines were found.
lines	A vector of the lines that needed to be drawn.
draw_arrow	If true, arrow heads will be drawn.

drawSegments() [3/4]

void OpenCVForUnity.XimgprocModule.FastLineDetector.drawSegments	(	Mat	image,
		Mat	lines,
		bool	draw_arrow
	)

		Mat	lines
	)

Draws the line segments on a given image.

Parameters

image	The image, where the lines will be drawn. Should be bigger or equal to the image, where the lines were found.
lines	A vector of the lines that needed to be drawn.
draw_arrow	If true, arrow heads will be drawn.
linecolor	Line color.
linethickness	Line thickness.
