◆ 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
imageA 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);
linesA 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()

int  linethickness 
)

Draws the line segments on a given image.

Parameters
imageThe image, where the lines will be drawn. Should be bigger or equal to the image, where the lines were found.
linesA vector of the lines that needed to be drawn.
