Low Rank Groupwise Deformations for Motion Tracking in Cardiac Cine MRI
Sean Rendell Jinming Duan
Diffeomorphic image registration is a commonly used method to deform one
image to resemble another. While warping a single image to another is useful,
it can be advantageous to warp multiple images simultaneously, such as in
tracking the motion of the heart across a sequence of images. In this paper,
our objective is to propose a novel method capable of registering a group or
sequence of images to a target image, resulting in registered images that
appear identical and therefore have a low rank. Moreover, we aim for these
registered images to closely resemble the target image. Through experimental
evidence, we will demonstrate our method's superior efficacy in producing
low-rank groupwise deformations compared to other state-of-the-art approaches.
