Methods

virtual
void
detect(
    InputArray src,
    OutputArray circles,
    Stream& stream = Stream::Null()
    ) = 0

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.
