In this talk, we will describe a new interactive procedure for segmenting 3D data sets using a mixture of ideas from control and image processing. More precisely, using a Lyapunov control design, a balance is established
between the influence of a data-driven gradient flow
and the human’s input over time. Automatic segmentation
is thus smoothly coupled with interactivity. An application
of the mathematical methods to orthopedic segmentation
is shown, demonstrating the expected transient and steady
state behavior of the implicit segmentation function and
auxiliary observer.
