Then how could I move only one of the shape Jul 17, 2014 · I have 2 contours and I want to compare how much the same are they, as the ratio of the area_of_c1/area_of_intersection and area_of_c2/area_of_intersection. We need to check above cases to find out if given rectangles overlap or not. They may have variations with slightly different backgrounds, dimensions, feature additions/subtractions, or transformations (scaled, rotated, skewed). My questions are: May 28, 2015 · From OpenCV doc:. jpg") # convert to grayscale base_gray = cv2. utils. resize(overlay_t, (fsize, fsize)) def overlay_transparent(background_img, img_to_overlay_t, x, y, overlay_size=None): """ @brief Overlays a transparant PNG onto another image A simple approach is to find contours, obtain the bounding rectangle coordinates using cv2. So far I managed to detect the edges using cv2. Sep 29, 2017 · I am trying to find/calculate the contour area in the next image: The goal is to delete all the dots you can see in image, so the blobs contoured with an area smaller than a value I give.
