public void detect(Mat _image, Mat _lines)
_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.public void drawSegments(Mat _image, Mat lines, boolean draw_arrow)
_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.public void drawSegments(Mat _image, Mat lines)
_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.Generated on Wed Oct 9 2019 23:24:43 UTC / OpenCV 4.1.2
