Data compression plays an important role by the digitization of the human body. In fact, 3D scanning processes generate very large amount of data, e.g. the head model of Figure 13 (center) corresponds to about 27 Mbytes of data. Therefore, for an efficient and unproblematic storage, treatment and visualization of the data, adequate compression processes are required. These can be defined specifically to the different parts of the human body by considering the typical topology of their surface. We take the human face as example: every human face is round shaped, has a nose, a mouth, two eyes, etc. This basic information is used to reach strong compression factors without loosing the important features of the human face. Figure 13 (right) shows an example of a 3D face model at two different compression factors: the details of the eyes, nose, and mouth are conserved, whereas the data resolution in areas with fewer details is reduced. 
In the special case of full body scanners, the systems are usually accompanied by software solutions for the determination of body sizes. Figure 14 shows some examples of such solutions, some of them works completely automatically extracting body sizes useful for tailoring or anthropometric applications, others permit the measurement of specific areas of the human body. The solutions are tailored specifically to the type of data resulting from the scanning process and therefore it is recommended to use software solutions only with scanning systems from the same manufacturer. 
Complete full body scanning solutions, coupling 3D scanners with software measurement solution, increased in the last couple of years the attractiveness of this technology for the fashion industry. As consequence, as it will be described in the next section, the number of applications in this specific domain increased.
