Are the car and building datasets available to the public?

Hi, I am getting the following error when I try to run it with the "-mbb" argument:

Traceback (most recent call last): File "main.py", line 124, in <module> connected_component, num_bands=args["num_bands"], sigma=args["mbb_sigma"] File "C:\Users\Khizar\Desktop\Projects\Proposals\Image Stitching\image-stitching main\src\rendering\multiband_blending.py", line 218, in multi_band_blending weights.append([cv2.GaussianBlur(weights[-1][i], (0, 0), sigma_k) for i in range(len(images))]) File "C:\Users\Khizar\Desktop\Projects\Proposals\Image Stitching\image-stitching main\src\rendering\multiband_blending.py", line 218, in <listcomp> weights.append([cv2.GaussianBlur(weights[-1][i], (0, 0), sigma_k) for i in range(len(images))]) NameError: free variable 'sigma_k' referenced before assignment in enclosing scope

hi

thanks for the repo, looks real cool and easy to use.

I gave a try at the code, to stitch 11 images. It toolk quite along time before I got the following message:

../image-stitching/src/rendering/simple_blending.py:68: RuntimeWarning: invalid value encountered in true_divide
  new_weights = (weights + image_weights) / (weights + image_weights).max()

I cannot share the images unfortunately, but they are 3kx4k (11Mpix) each, for a total size of about 45Mo.

Any idea? Could it be that an image could not get connected to the others?
