◆ 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
src8-bit, single-channel binary source image.
linesOutput 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 ( \(0 \sim \textrm{vertical line}, \pi/2 \sim \textrm{horizontal line}\) ).
streamStream 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_linesResult of cuda::HoughLinesDetector::detect .
h_linesOutput host array.
h_votesOptional output array for line's votes.
streamStream for the asynchronous version.
