Abstract
This paper describes a method for the accurate recovery of time-varyin
g 3D shapes with known cycle from images with different. viewpoints as
well as times, aiming at the recovery of the left ventricular shapes.
ur recovery method is based on the integration of apparent contours f
rom different viewpoints. We perform direct fitting to a 4D closed sur
face model based on B-splines so as to deal with fragmented contours s
uch as extracted from x-ray cineangiocardiograms. The method is quanti
tatively evaluated using synthesized and real image sequences.
