Hi, I am new to OpenCV. I draw lines and circles on paper and want to detect them using OpenCV. But it detects the whole picture as a line. What do I do wrong?
Hi Tetiana06, To be honest, I have no idea how to do this either, but have you seen this article: https://www.learnopencv.com/tag/circle-detection/ it seems to be right in line with the goal.
