Hello everyone ..

i would like ask about how to use HoughCircles detection using GPU under opencv 2.9.11 (not 3.0.0) i have managed to use gpu::Houghlines, i found a sample how to use gpu::houghlines in the sources samples but i can't figure it out how to use gpu::HoughCirlces it took me days now i have not found anything around the internet so hopefully i will find an answer here

thank you .

Hi,

If you have managed to use gpu::HoughLines, you should be able to use gpu::HoughCircles.

It seems for me at first sight that you just have to supply the correct arguments like for gpu::HoughLines or you should be more explicit on what you cannot do: convert an image to grayscale ?, load a cv::Mat to cv::GpuMat ?, the correct values for the arguments ?, how to get / display the result ?, etc.

For the cpu version of cv::HoughCircles, the corresponding tutorial.

yes i want to know ho to call the gpu::houghcricles as i understood its a bit diffrent from the cpu version its not the same way to call it and display the results so what i want is how to detect the circles and display them

The function arguments and call can be found in that link. What more do you need to know?

Once performed than use the download function beneath that to retrieve the hough circle data in a normal Mat object instead of a GpuMat object.
