Web1 de dez. de 2024 · OpenCV provides us several methods for that. In our code, we will use the function cv2.findContours (). This method requires three parameters. The first is the source image. The second argument is Contour Retrieval Mode which is used to determine the hierarchy between contours. Webopencv_contours_to_polygons.py. This script allows the user to convert the contours hirarchy generated by cv2.find_contours () into a list of Shapely polygons. """Generates a list of Shapely polygons from the contours hirarchy returned by cv2.find_contours (). The list of polygons is generated by performing a depth-first search on the contours ...
