Another type of classification is outlier selection or contamination identification. As an example, in Fig. 4.23(b), the butter is the desired material and bacteria the contamination. An arbitrary threshold for this image would be 0.02, in which all pixels >0.02 are considered suspect, and hopefully, because this is a food product, decontamination procedures are pursued. In these two examples of classification, only arbitrary thresholds have been defined and, as such, confidence in these classifications is lacking. This confidence can be achieved through statistical methods. Although this chapter is not the appropriate place for an involved discussion of application of statistics toward data analysis, we will give one example often used in chemometric classification.

Nanofibrous mats can also act as ion exchangers [45,46] which have faster kinetics compared to the classical, granular systems. SEM image of pollens of Aesculus hippocas-tanum filtered by electrospun media can be seen in Figure 10.3. It is worth mentioning that nanofibers have approximately two orders of magnitude lower p>ore size than the size of the pollens, therefore even smaller items can be filtered such as bacteria, which points to the biomedical applications of electrospun nanofibers. 

Identification of marine zooplankton using image processing was one of the earliest ATT applications (Katsinis et al., 1984). Bacteria have also been the object of ATI research (Blackburn et al., 1998 Dorge et al., 2000 Walker and Kumagai, 2000 Foreroa et al., 2004).
