Editing 3D binary images using distance transforms

A method for editing 3D binary images using distance information is presented. The distance transform of the whole image, i.e., of both the object and the background, is used to simultaneously remove object protrusions, cavities and components of negligible size. Our method can be useful when smoothing of an object is needed, e.g., for removal of noise before computing the skeleton of an object. It can also be used to guide decomposition of a complex objects consisting of components with different thickness. Preliminary results of the decomposition algorithm are shown
