Images on zenodo are all-black-image

[XiaoXiLe2023]

Thanks for your project!

I download images.tar.gz on zenodo and unzip it.
All of the images are black tif files wth the size of 366KB.

If there is nothing wrong with it, how can I transfer it into RGB image?

Please check the actual image data arrays - they should not be all zero. The images might appear black due to insufficient scaling. What I typically do is to scale each band based on its minimum and maximum values: x_scaled = a+b*(x-min(x))/(max(x)-min(x)), where x is one of your bands; you can start with a=0 and b=1 and then experiment with a and b to get nice images. Also, keep in mind that the image data has 13 bands; RGB is located in bands 4, 3, 2, respectively.
