人臉辨識是近年來很熱門的研究，希望透過人臉辨識來達到身份的識別，而省去以往在不同的服務及場合下需要配戴很多張不同的證件。為此發展出來之人臉辨識，我們稱它為「使用者配合環境」，是在想要索取服務的情況下，進而配合攝影機來執行人臉辨識；反之在監視系統中，有人自然的從走廊經過，我們想透過走廊內的攝影機知道他是誰，在過程中該人並未配合攝影機來執行人臉辨識，所以像這類的情況我們稱它為「非使用者配合環境」，在本論文中將討論兩者之差異。文中我們透過在階梯教室裡不經由學生配合的情況下來執行人臉辨識，藉此來討論人臉辨識如何實現在非使用者配合環境下。

The researches of face recognition have been more and more popular in recent years. In different services and occasions, we need a lot of certificates to provide identity. By using the face recognition, we could save the paperwork. Therefore, the face recognition is developed by the above-mentioned that we call "Cooperative User Environment". It's a service which coordinates with the camera to implement the face recognition. On the other hand, we would like to know the person who passes through the corridor in the surveillance system. In this process, the person doesn't coordinate with the camera to implement the face recognition that we call "Non-Cooperative User Environment". In this paper, we will discuss the differences between cooperative user environment and non-cooperative user environment. We use the face recognition to make a roll call in the ladder classroom without the students' cooperation. In the experiments, we could know how the face recognition is implemented in the non-cooperative user environment.
