Abstract
The problem of tracking and quantifying the nonrigid nonuniform
motion of naturally occurring annuli from image sequences is addressed.
Motion computation is performed in two different manners, i.e., shape
adherence with second order difference smoothing, and shape adherence
with smoothing based on strain energy minimization. Results are shown
for two typical applications, i.e., motion of the left ventricular wall
of the heart over an entire cardiac cycle as derived from magnetic
resonance images, and extension of neuronal growth cone membranes
(lamel-lipodia) from light microscopy images
