Face Detection and Modeling for Recognition - Biometrics Research ...

can recognize known faces in caricature drawings (e.g., faces shown in Fig. 1.6) and
cartoons (see Fig.1.7) without any difficulty has not been fully explored in research
studies on face recognition [48], [49], [50], [51].

identification.

Figure 1.7. Cartoons reveal that humans can easily recognize characters whose facial
components are depicted by simple line strokes and color characteristics: (a) and (b)
are frames adapted from the movie Pocahontas; (c) and (d) are frames extracted from
the movie Little Mermaid II. (Disney Enterprises, Inc.)
in Fig. 1.6 are represented only by strokes (geometrical features), while some others
have parts of facial features dramatically emphasized with some distortion. Cartoon
faces are depicted by line drawings and color without shading.
People can easily
identify faces in caricatures (see, Fig. 1.6) that exaggerate some of the facial components/landmarks.
Besides, we can also easily identify known faces merely based on
some salient facial components. For example, we can quickly recognize a known face
