The code works just for one image

[Ng-ms]

i tried the code with my image (512x512 ) but it did not work , what can i change to make it work for my data ?

What error do you get? If you resize your image is it working?

this is the error , i tried resize it as BW.png image but it gives the same error

It seems that your matrix delD_xn is empty. What is the results of print(mir_delD_yn.shape)?

Same issue.

How to solve it?

Check the outputs of this line to be correct and non empty:
D,IDX = morph.distance_transform_edt(BW,return_distances=True, return_indices=True)
