IC694MDL752 該實驗中,選定a的值為12 400,b的值為16 200,這兩個值的確定需要進行大量的實驗,從中找出規律。x的值的大小直接影響識別的效果,文中分別選取x=4和x=5進行了測試。
(1)x=4時:程序在測試可識別庫中的分屬12個人的36幅人臉圖像時,正確識別出其中的33幅,其余3幅圖像均被判否,0個判錯。程序在測試不可識別庫中的分屬3個人的33幅人臉圖像時,22幅圖像被成功判否,11幅被誤判;
(2)x=5時:程序在測試可識別庫中的分屬12個人的36幅人臉圖像時,正確識別出其中的25幅,其余ll幅圖像均被判否,O幅判錯。程序在測試不可識別庫中的分屬3個人的33幅人臉圖像時,28幅圖像被成功判否,5幅被誤判。
分析上面的實驗數據可知,x=4時,可識別庫的識別率為91.6%,不可識別庫的判否率為66.7%。x=5時,可識別庫的識別率為69.4-%,不可識別庫的判否率為84.8%。因此,應用于不同的場合時,應選擇不同的x值,當要求盡可能拒絕外來人臉時,可選x值為5,當要求盡量識別已知人臉時,可選x值為4。
5 結束語
此人臉識別系統的構建,充分考慮了其推廣性,未采用USB攝像頭作為圖像采集設備,而以通用視頻標準的模擬攝像頭取而代之,因此用戶在攝像頭選擇的時候,可以更加自由。同時該設備支持多種接口輸入,除了普通的R-jack口之外,還提供了Svideo,YPbPr和RGB等輸入方式。該設備的識別精度可達90%以上,基本滿足了識別要求。系統實時性好、攜帶方便,可以通過程序的修改推廣到動態圖像跟蹤、運動檢測等領域。
