Web4 de jul. de 2024 · The HoughCircles () function finds circles on grayscale images using a Hough Transform. The name is the same in both python and c ++, and the parameters it takes are the following: image – Grayscale input image circles – Output vector of found circles. This vector is encoded as 3-element floating-point vector (x,y,radius). WebOpenCV already comes with a function to perform hough transforms. It lets you choose between different variants of the transform: the standard hough transform, the probabilistic hough transform and the multi-scale hough transform.Here I'll get into the technical details of getting the command, cvHoughLines2, to work.The command expects and …
