§ detect()

virtual void cv::cuda::HoughSegmentDetector::detect ( InputArray  src,
OutputArray  lines,
Stream stream = Stream::Null() 
)
pure virtual

Finds line segments in a binary image using the probabilistic Hough transform.

Parameters
src8-bit, single-channel binary source image.
linesOutput vector of lines. Each line is represented by a 4-element vector \((x_1, y_1, x_2, y_2)\) , where \((x_1,y_1)\) and \((x_2, y_2)\) are the ending points of each detected line segment.
streamStream for the asynchronous version.
