Thank you for your response. This issue was generated by performing practical operations on your original Brahmaputra_Braided_River data. Now, I am using my own data for the operations, but a new issue has arisen: the skeleton obtained for the river does not match the original image. The attached files include test.tif, which is my original mask, and Cdm_channel_skel.tif, which is the skeleton image I obtained.

Hi @zhaoshaohua21, this error almost certainly indicates that something is wrong in your upstream processing, OR that the default parameters to compute_mesh() are insufficient for your case. There is no way for us to know without having a minimal, reproducible example to process ourselves. Can you share the mask that you're processing so we can take a look?

I have resolved the issue and am very grateful for the inspiration provided by your package. Additionally, I would like to share a geographic imaging plugin for Photoshop. By configuring this plugin in Photoshop, you can process images with georeference information that are imported into the software, and the exported images will still retain their georeference information. This provides some convenience for the initial mask processing.

I will look at your data later, but if you're getting errors when running
through the examples (without changing anything), the problem is almost
certainly wrong package versions.

Hello, I encountered this issue while calculating curvature. I have checked the skeleton image and found no problems.
>> skeleton_image = 'K:/Meandering_River/Results/skel.tif'
>> curvature_map = im_utils.skel_pixel_curvature(skeleton_image, nwalk=4)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "C:\Users\zsh\.conda\envs\myenv\lib\site-packages\rivgraph\im_utils.py", line 1342, in skel_pixel_curvature
py = np.ndarray.tolist(skelpix[:, 0])
IndexError: index 0 is out of bounds for axis 1 with size 0
