An An system can take two forms fuUy automated aud sani-automated (Chesmore, 2000). Fully automated ATI does not require auy user interaction and is suitable for long-term unattended operation - for example, in forest biodiversity studies. Semi-automated ATI is simpler to achieve and produces a partial identification or an identification that is verified by the user. The latter is likely to be more acceptable in the short term as it keeps the user in the loop . Semi-automated systems also allow for a degree of user interaction - for example, to select objects within an image field of view for identification. In terms of schematic design, an ATI system is basically a standard pattern recognition system, as shown in Figure 6.1, and is divided into four distinct functional blocks sensor, preprocessor, feature extractor aud classifier. Each stage is described next in more detail. 

In 1990, while starting a biodiversity study of the yeast flora in wet and dry forests of central Africa, it became obvious that identification using conventional methods was barely possible. The standard physiological tests were tedious, slow and difficult to interpret unambiguously, and the identification of isolates using the classical dichotomic keys was very difficult. As a consequence.
