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.

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
