The invention provides a method of providing a volumetric representation of a three-dimensional object. A plurality of voxels are defined in a three dimensional space, and voxels are categorised as either foreground or background according to at least one silhouette image of the object. Foreground voxels are assigned a first binary value, and background voxels a second binary value. An intermediate value is assigned to voxels, preferably according to an estimate the ratio of foreground to background contained within said voxel, thereby providing more information than just first and second binary values . Several examples are given for how to determine the proportion, or fraction, of each voxel or portion thereof. |
