本論文的研究目的為人臉表情之視覺辨識分析,主要是利用人臉五官的在各種表情下的變化不同,人臉分割成不同的區域,每個區域採取不同的擷取方式,來記錄特徵。在擷取特徵的部份主要是利用各區域灰階值的相對差異性,測邊運算之類,這些都是屬於相對值的當作門檻,可以避免利用色彩所造成的誤差。最後再利用人臉在無情緒時的狀態和有表情的狀態的特徵值差異所造成的特徵值量,透過訓練好的類神經網路來判別人臉表情的情緒。本論文從影像抓取出人臉所在矯正後,自動去擷取各人臉表情的特徵座標,最後透過類神網路的比對輸出結果,將以上的流程,整合成一套自動化的人臉表情辨識系統。
This research studies techniques of interpret facial expressions for ordinary people.
In this research work, the facial expression analysis is composed of three steps. Firstly, the face is extracted and recognized from an image with a possibly complex background. Secondly, important features such as the location and size/shape information of eyes, eyebrows, nose, and mouth are extracted and measured to calculate characteristic vectors. Finally, a back-propagation neural network after training is used to interpret facial expressions. This facial expression interpretation system is a fully automatic program and is integrated into the intelligence program for the intelligent robot, DOC-2.
