Web5 de ago. de 2024 · To create an array compatible with OpenCV simply cast to np.uint8 and multiply by 255: sk = np.array(sk, dtype=np.uint8) sk *= 255 Note that, when dealing with NumPy arrays, you generally don't need to loop over all pixels. In fact, it's worth trying to avoid doing so, as loops in Python are extremely slow. This is my relevant code for applying the thinning. I have also tried the 'thin' function instead of 'skeletonize' but the results are similar. from skimage.morphology import skeletonize, thin new_im = cv2.imread(im_pth) gray = cv2.cvtColor(new_im, cv2.COLOR_BGR2GRAY) ske = (skeletonize(gray//255) * 255).astype(np.uint8) cv2.imshow("image ...
