In this paper, we extend a computationally efficient framework for tracking of deformable subdivision surfaces in 3D echocardiography with speckle-tracking measurements to track material points. Tracking is performed in a sequential state-estimation fashion, using an extended Kalman filter to update a subdivision surface in a two-step process: Edge-detection is first performed to update the model...
In this paper, we present an extension of a computationally efficient Kalman filter based tracking framework to allow simultaneous tracking of several deformable models in volumetric data. The models are coupled through shared transform nodes in a hierarchical structure to enforce common position, orientation and scaling, but are allowed to alter shape independently. Automatic tracking of the endo-...
