Hi Ratan,

It may happen when your input images are captured in different light conditions.
Make sure that the common regions of each two images are in the same light condition.

Hope it useful.

All your images are captured in the same exposure, right. But the left and the right sides of the images seem like not similar. I guess your images are from a microscope, and that may cause the problem. This algorithm will work more properly in ordinary images.

Yeah,it is working fine for ordinary images,but my project is on microscopic images :(
Is there any way to remove those dark bands?

I am not sure about this. But I think you should try some pre-processing methods to make your image more homogeneous. Try with histogram equalization.

Waiting for someone successfully dealing with this thing here.

Hi, your repo is very helpful. I'm wondering how to stitch more pictures together. When I stitched 20 pictures, it turns out "failed". If I stitch these pictures one by one, like in a for loop, then the stitched pic cannot be stitched with another one. Do you have any idea about this? Thanks in advance.

hi BunnyIcon, did you try with multi_image_pano.py, you can see the command for running at my instruction there.
