About how to preprocess Vaihingen dataset labels！

[dongfeicui]

Since the url of Vaihingen dataset has expired, and the labels of the dataset found on the Internet do not satisfy the current project, I would like to share with you how I deal with the labels.

Here is my code. Welcome star and follow me!

At present, I only uploaded how to preprocess labels and other places that need to be modified in the project, and I will update it later.

Whether the point-level label images are single-channel or three-channel？
