Smoothing aorta segmentations across time

Community

Good afternoon,

I’m working with aorta segmentation across different cardiac frames and I was wondering if there is any way to smooth the segmentations across time (different cardiac frames) to avoid segmentations inconsistencies between time points.

I would appreciate any suggestions or recommendations to address this issue.

Thank you in advance =D

You could try using sequence registration to take one segmentation and deform it across time instead of having a separate segmentation for each frame. This will likely result in a more consistent appearance over time because the registration will only introduce smooth deformations.
