7-13 空間周波数を用いた表情認識の試み(第7部門 画像・動画処理)

抄録

We investigated facial expression recognition using spatial frequency filtering of facial images (happiness, sadness, surprise, fear, anger and disgust). Spatial frequency components in low and middle range were used for recognition. The results show that "surprise", "happiness", "anger" and "sadness" were recognized well, however, the correct recognition rate of "fear" and "disgust" was low.
