Abstract

This paper describes a novel, 2D+time Active Appearance Motion Model (AAMM). Cootes's 2D AAM framework was extended by considering a complete image sequence as a single shape/intensity sample. This way, the cardiac motion is modeled in combination with the shape and image appearance of the heart. The clinical potential of the AAMMs is demonstrated on two imaging modalities - cardiac MRI and echocardiography.
