Abstract

Digital image processing is applied to extract and measure features and structures in images. Different stages of processing can be distinguished (Fig. 5.1). The image data is transformed in each processing step.

The first steps, imaging, sampling and quantization, lead to digital images [32]. The imaging is commonly performed with physical devices transforming a band of the electromagnetic spectrum into an imaging function, which is then digitized spatially and concerning its amplitude. The spatial digitization is frequently called sampling. The digitization of the amplitude is referred to as quantization.
