It seems there is a problem with OpenCV Hough implementation on GPU. Application: apply gpu::Hough on a video: it counts 664 objects. Close Application. Restart the same application on the same video: it counts 691 objects. Close Application. Restart the same application on the same video: it counts 667 objects.
Using Opencv Hough on CPU the count is always 662 objects. How is it possible? Thank you
