Figure 9

Examples of images used in this paper. The variations of probe samples in AR are neutral, smile, angry, scream, sunglass, and scarf, while the variations of probe samples in JAFFE are neutral, smile, angry, surprised, sad, disgust, and fear. FERET probe samples’ variations, however, consist of mixtures of several different expressions while CK+ consists of several FACS-coded expressions.
