This book is a detailed description of the basics of
three-dimensional digital image processing. A 3D digital image
(abbreviated as "3D image" below) is a digitalized representation
of a 3D object or an entire 3D space, stored in a computer as a 3D
array. Whereas normal digital image processing is concerned with
screens that are a collection of square shapes called "pixels" and
their corresponding density levels, the "image plane" in three
dimensions is represented by a division into cubical graphical
elements (called "voxels") that represent corresponding density
levels. Inthecontextofimageprocessing,in
manycases3Dimageprocessingwill refer to the input of multiple 2D
images and performing processing in order to understand the 3D
space (or "scene") that they depict. This is a result of research
into how to use input from image sensors such as television cameras
as a basis for learning about a 3D scene, thereby replicating the
sense of vision for humans or intelligent robots, and this has been
the central problem in image processing research since the 1970s.
However, a completely di?erent type of image with its own new
problems, the 3D digital image discussed in this book, rapidly took
prominence in the 1980s, particularly in the ?eld of medical
imaging. These were recordings of human bodies obtained through
computed (or "computerized") tomography
(CT),imagesthatrecordednotonlytheexternal,visiblesurfaceofthesubject
but also, to some degree of resolution, its internal structure.
This was a type of image that no one had experienced before.
