Abstract:	眼睛是臉部最重要的特徵，眼睛的定位在人臉辨識與虹膜辨識是一個前置的動作，如果能夠快速簡單萃取眼睛的特徵，找到眼睛的位置，對於之後的辨識就能夠有顯著的效果。本研究目的在於提出一種利用橢圓蓋伯濾波器，來定位眼睛位置，我們建立一個橢圓蓋伯濾波器針對眼睛大小、頻率，來定位眼睛的位置，透過蓋伯濾波器對於紋理強大的能力，橢圓蓋伯濾波器匹配眼框，圓形蓋伯濾波器匹配眼珠，結合兩者，能夠更精確的定位眼睛位置，透過實驗與其他方法比較，我們所提出的這個方法有較高的定位率。關鍵字: 蓋伯濾波器，眼睛定位，橢圓蓋伯濾波器。 The eyes are the most important facial landmarks on human face. Eyes localization in face recognition and iris recognition is a very important preprocessing. It’s easy to find the location of eyes if we can quickly and easily extract the characteristics of eyes. This paper presents a method, based on elliptical Gabor filters (EGFs), to locate the positions of eyes. According to the size and the frequency of the eye, we can create an EGF to locate the eye. The EGF can be exploited to segment the eye regions. And the circular Gabor filter (CGF) can be used to locate the pupil. Therefore, the combination of EGF and CGF can find the positions of eyes more precisely. Compared with other approaches, the proposed approach has higher recognition rates. Keywords: Gabor Filter, Eye Location, Elliptical Gabor Filter
