WebThe most straightforward way is to loop over the contour points manually, and draw a circle on the detected contour coordinates, using OpenCV. Also, we use a different image that … WebIn OpenCV, finding contours is like finding white object from black background. So remember, object to be found should be white and background should be black. There are three arguments in cv.findContours function, first one is source image, second is contour retrieval mode, third is contour approximation method.
