Volumetric digital images are three-dimensional image arrays corresponding to a stack of two-dimensional slices, produced for instance by a tomographic scanner. Such images play an important role in various applications, especially in medical image processing, in the processing of seismic data and in many other domains. Written by a computer vision specialist, this clear, detailed account of volumetric image analysis techniques provides a practical approach to the field including the following topics: preprocessing of volumetric images, obtaining quantitative measurements in volumetric images, detection and modelling of objects in volumetric images.
