摘要

本論文所開發的系統由人臉偵測與人臉辨識所組成。人臉偵測常常作為人臉辨識的前置作業，其結果足以影響整個系統的效能。由於本系統是即時系統，所以快速、準確地定位出人臉區域是本文人臉偵測系統的主要目標。
當影像輸入時，辨識系統先根據色彩資訊自背景中分離出可能有人臉存在的區域，接著以形態學的方法在可能是人臉的區域中萃取出可能是臉部特徵的區塊，然後再以臉部特徵的色彩資訊以及眼睛與嘴唇的幾何關係定位出正確的人臉位置，最後再以Fisherface的方法進行辨認。

The system developed in this thesis consists of face detection and recognition sub-systems. Face detection usually serves as a pre-processor in face recognition systems. This process will affect the performance of the recognition system. Because the proposed system is a real time system, locating the face region rapidly and precisely is one of the main goals of this thesis. First, the recognition system separates the face candidates from the background by color information when image is acquired. The system identifies the eyes and lip candidates from face candidates by morphologic methods. Next, the system locates the real face region by color information and the geometrical relation of eyes and lips. Finally, the recognition process is performed by applying Fisherface algorithm.
