The theory, design, implementation and evaluation of a three-dimensional surface detection algorithm
Ehud Artzy, Gideon Frieder, Gábor T. Herman · 1980
In many three-dimensional imaging applications the three-dimensional scene is represented by a three-dimensional array of volume elements, or voxels for short. A subset Q of the voxels is specified by some property. The objects in the scene are then defined as subsets of Q formed by voxels which are “connected” in some appropriate sense. It is often of interest to detect and display the surface of an object in the scene, specified say by one of the voxels in it.
