Figure 17. The <strong>facial</strong> areas involved in the feature extraction process<br />
The discretization process started after all the FCP files were loaded into the memory.<br />
For each parameter, the system searched for the minimum and maximum value. Then the<br />
values were used to create an interval that includes all the sample values. Given the<br />
number <strong>of</strong> distinct classes to exist following the discretization process, the interval was<br />
split in a number <strong>of</strong> pieces equal to that <strong>of</strong> the classes (Figure 18).<br />
Figure 18. Discretization process<br />
The result <strong>of</strong> the discretization process is presented in Listing 4.<br />
