Have completed a PhD on algorithms for real-time tracking of deformable models in volumetric data, using sequential state estimation. The primary application was automatic left ventricular segmentation in 3D echocardiography.

As part of my PhD, I developed the world's fastest algorithm for 3D segmentation and tracking with deformable models. The developed tracking framework operated 10-100 times faster than known comparable systems, with typical execution times of 5 ms per model per frame on standard computer hardware.


Examples of automatic 3D segmentation/tracking conducted in real-time:
Endocardial LV segmentation with a Doo-Sabin surface.
Endocardial and epicardial LV segmentation with two coupled Doo-Sabin surfaces.
Tracking of LV endo+epi and RV in cardiac CT.
Automatic bladder segmentation.
