◆ detect()

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

Finds circles in a grayscale image using the Hough transform.

Parameters
src8-bit, single-channel grayscale input image.
circlesOutput vector of found circles. Each vector is encoded as a 3-element floating-point vector \((x, y, radius)\) .
streamStream for the asynchronous version.
