It is apparent that the eyes, nose, <strong>and</strong> mouth regions are also useful for recognition.<br />
Humans also recognize faces using these features. We also extracted these regions based<br />
on l<strong>and</strong>mark points around them for face recognition as shown in Figure 22. Here, we<br />
need to also find out how to perform optimum weighting since those regions work<br />
differently in the recognition stage.<br />
