Usine Multiscale Medial Models to Guide Volume Visualization

We present a hybrid volume rendering method that uses object shape information provided by multiscale medial models to guide a splatting renderer. Such models can efficiently give largetolerance versions of object boundaries. Our renderer uses the medially implied boundaries to focus the rendering effort towards the region of detailed boundaries, thereby avoiding occlusion of the objects of interest. Our renderer finds a most likely boundary displacement from the medially implied boundary using a Bayesian approach based on the volume directional derivatives of image intensity in directions normal to the medially implied boundary.
