Hi!

Even after trying to change several parameters (Pano confidence threshold, type of matcher used...), I cannot get OpenCV's high level stitching API to stitch these two images (originals can be found here: http://imgur.com/a/oFc67)

The images don't seem that much different to me. The error I get is ERR_NEED_MORE_IMGS: OpenCV cannot identify these two images are part of the same panorama, while when trying in Hugin or PTGui, I have no issue stitching these two. Any idea what I might be doing wrong?

Thanks!

stitching.cpp is successful on your images

You may want to also normalize exposure. The two images seem differently exposed, especially if you look in the inside of the image above the stairs.
