Hi there,
We have acquired an ultrasound sequence with approxamtely 1200 frames and due to the fact that there were lots of hand motion during the acquistion, I need to apply some correction alogorithms.
I was thinking to use image registration using the Imregister function and have my first frame as my fixed image and apply registation to rest of the frames in reference to the first frame.
I have been thinking to use the foor loop, but this is taking forever and it doesnt seem to break out of the loop and finish the process.
Do you guys have any idea of how can I overcome this issue?
All the best,
Nikan

Maybe downsample the images to reduce computation and use imregtform() instead of imregister()?
