1. An apparatus for processing at least one central voxel in a neighborhood of voxels of a multi-dimensional scene of at least three dimensions, comprising: acquisition means for acquiring a first plurality of signals, each of said signals representative of a voxel, a plurality of said voxels representative of a multi-dimensional scene of at least three dimensions, said plurality of said voxels arranged in rows, said voxels equally spaced along said rows, said rows in parallel to each other; storage means for storing said first plurality of signals representing said multi-dimensional scene; first retrieval means for retrieving at least one of said first plurality of said signals representative of at least one central voxel; second retrieval means for retrieving a second plurality of said signals representative of at least one multi-dimensional neighborhood of at least three dimensions around said at least one central voxel, said second plurality of said signals being substantially a subset of said first plurality of said signals; pattern means for providing a plurality of pre-determined pattern signals representative of an plurality of pre-determined multi-dimensional neighborhoods of at least three dimensions around at least one pre-determined central voxel; comparison means for comparing said second plurality of said signals representative of said multi-dimensional neighborhood of at least three dimensions around said at least one central voxel to said pre-determined pattern signals; processing means for processing said at least one central voxel in response to said comparison means; and transmitting means for transmitting said at least one processed central voxel.
