detect()

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

pure virtual

Finds lines in a binary image using the classical Hough transform.

Parameters

src	8-bit, single-channel binary source image.
lines	Output vector of lines. Each line is represented by a two-element vector \((\rho, \theta)\) . \(\rho\) is the distance from the coordinate origin \((0,0)\) (top-left corner of the image). \(\theta\) is the line rotation angle in radians ( \(0 \sim \textrm{vertical line}, \pi/2 \sim \textrm{horizontal line}\) ).
stream	Stream for the asynchronous version.

downloadResults()

virtual void cv::cuda::HoughLinesDetector::downloadResults ( InputArray  d_lines, OutputArray  h_lines, OutputArray  h_votes = noArray(), Stream &  stream = Stream::Null()  )

pure virtual

Downloads results from cuda::HoughLinesDetector::detect to host memory.

Parameters

d_lines	Result of cuda::HoughLinesDetector::detect .
h_lines	Output host array.
h_votes	Optional output array for line's votes.
stream	Stream for the asynchronous version.
