Automatic segmentation and tracking of biological prosthetic heart valves

Prosthetic heart valve designs must be rigorously tested using cardiovascular equipment... ...Using video frames recorded with a high-speed digital camera during in vitro simulations, an initial estimation of the orifice area is first obtained via active contouring and thresholding and then refined to capture the leaflet free edges via a curve transformation mechanism. Results: Experiments on video data from pulsatile flow testing demonstrate the effectiveness of our approach...
