## Member Function Documentation

## ◆ 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

  src | 8-bit, single-channel grayscale input image.
  circles | Output vector of found circles. Each vector is encoded as a 3-element floating-point vector \((x, y, radius)\) .
  stream | Stream for the asynchronous version.
