摘要
人臉識別技術可以應用于基于網(wǎng)絡的身份認證，我們實現(xiàn)了基于WebCam的人臉識別與跟蹤系統(tǒng)。本文以WebCam采集的視頻流為數(shù)據(jù)源，截取視頻流中的單幀圖像，通過轉換色彩空間、人臉膚色建模、后處理操作和人臉定位算法實現(xiàn)了人臉檢測，并以此為基礎實現(xiàn)了在視頻流中對于人臉的跟蹤。試驗結果表明，我們所實現(xiàn)的人臉識別算法適用于近距離人臉的檢測，可以應用于基于WebCam的身份認證。

Abstract
Face recognition can be applied to identity authentication on Internet, now we have realized face recognition and tracking system based on WebCam. This essay takes video flowing collected from WebCam as data source, and cuts off Single frame in video flowing. It has realized face detection through transforming colored space, complexion modeling, aftertreatment and face orient algorithms, and based on which the essay has realized face tracking in video flowing.The result of the test shows that the face detection algorithms we realized adapts to short distant face detection, and also can be used as identity authentication based on WebCam.
