OpenCV Error: Iterations do not converge (The algorithm stopped before its convergence. The correlation is going to be minimized. Images may be uncorrelated or non-overlapped) in cv::findTransformECC, file C:\build\master_winpack-build-win64-vc14\opencv\modules\video\src\ecc.cpp, line 540

When I use the code you supply in image alignment, I uploaded two .png file, sometimes it can run correctly, but sometimes it won't and shows the title error. Could you help me to figure it out?
Thank you!

You should make sure you are using the correct versions.

You should make the title of this issue less long :)

@wutao720912 have the same problem. How to ignore the error. It broken progress.

If the algorithm does not converge, it means it may not be the right one for these set of images. You should check our feature-based image alignment.

@spmallick I have to read that paper on ECC because if it s not feature-based, I am unsure what it is based on.
