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);`

lines

Type: OpenCvSharpOutputArray
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.
