The inducement analysis of local facial expression recognition

It is possible that human and computer give a different recognition results in facial expression recognition. This paper points out that one class of expression may be induced of various mental inducements, so it is more important to judge the inducements of a facial expression than to identify the class of a facial expression. In this paper, two local regions such as mouth and eye that are extracted from CED-WYU(1.0). The mouth images are used to analyze the expression inducements. And the experiment results explain our understanding about expression recognition.
