We describe an algorithm for 3D interactive surface extraction by non-rigid implicit template deformation, with two main original features. First, our formulation incorporates user input as inside/outside labeled points to drive the deformation and improve both robustness and accuracy. This yields inequality constraints, solved using an Augmented Lagrangian approach. Secondly, a fast implementation of non-rigid deformation enables interactions with a live visual feedback of the deformation. We validate this technique in Contrasted Enhanced Ultrasound images of kidneys in preoperative radio-frequency ablation planning.
