Research
Have completed a PhD on algorithms for realtime 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 10100 times faster than known comparable systems, with typical execution times of 5 ms per model per frame on standard computer hardware.
Examples
Examples of automatic 3D segmentation/tracking conducted in
realtime:
Endocardial LV segmentation with a DooSabin surface.

Endocardial and epicardial LV segmentation with two coupled DooSabin surfaces.

Tracking of LV endo+epi and RV in cardiac CT.

Automatic bladder segmentation.
