This paper reports an optical based method for quantification of cardiac motion in MRI
images. The cardiac motion is quantified in a Short-Axis (SAX) slice located at the mid-cavity
of the left ventricle. In this slice, the left ventricle wall is segmented for extracting the
endocardium, the epicardium and the mid‑wall. The velocity field for these contours is
available after performing the optical flow estimation for the given slice. Post-processing of
this motion field enables estimation of the radial displacement. The core of this cardiac …
