This chapter gives an introduction to the methods of biomedical image

processing. After some fundamental preliminary remarks to the terminology used,

medical imaging modalities are introduced (Sect. 1.2). Sections 1.3 and 1.4 deal

with low-level image processing and visualization, respectively, as far as necessary

to understand the following chapters. Subsequently, the core steps of image

analysis, namely: feature extraction, segmentation, classification, quantitative measurements,

and interpretation are presented in separate sections. On account of

its high relevance, the focus is on segmentation of biomedical images. Special segmentation

methods and techniques have been developed in the medical application

domain.
