In this paper we present an evaluation of a robust visual image tracker
on echocardiographic image sequences. We show how the tracking framework
can be customised to define an appropriate shape-space that describes
heart shape deformations that can be learnt from a training data set. We
also investigate an energy-based temporal boundary enhancement method to
improve image feature measurement. Preliminary results are presented
demonstrating tracking on real normal heart motion data sequences and
synthesised and real abnormal heart motion data sequences. We conclude
by discussing some of our current research efforts.
