Model-based segmentation and analysis of brain images depends on anatomical knowledge which may be derived from conventional atlases. Classical anatomical atlases are based on the rigid spatial distribution provided by a single cadaver. Their use to

In image analysis applications, segmentation of gray-level images into meaningful regions is an important low-level processing step. Various approaches to segmentation investigated in the literature, in general, use either local information of gray-l

Publisher Summary This chapter analyzes the method of tricubic interpolation. In many cases, linear interpolation provides a very good compromise between speed and accuracy. However, when the data volume is non-isotropic, linear interpolation may int

Registration of Magnetic Resonance (MR) and Positron Emission Tomographic (PET) images is a crucial step in multi-modality brain image analysis. We have developed a technique which we call iterative principal axes registration (IPAR). Using this meth

An anatomical knowledge-based system for image analysis that interprets CT/MR (computed tomography/magnetic resonance) images of the human chest cavity is reported. The approach utilizes a low-level image analysis system with the ability to analyze t
