指紋圖像評(píng)估流程
在指紋采集輸入過程中，由于手指的指紋質(zhì)量、安放位置及干濕狀態(tài)等原因，都可能無法正確識(shí)別指紋信息。為提高指紋識(shí)別效率，先對(duì)采集的指紋信息進(jìn)行評(píng)估。安全控制器對(duì)指紋圖像進(jìn)行指紋灰度圖像隔點(diǎn)采樣，指紋圖像點(diǎn)方向圖計(jì)算，指紋灰度圖像的前、背景圖分離，指紋前景圖面積分析，指紋圖像質(zhì)量分析等圖像處理過程，并對(duì)評(píng)估的結(jié)果用漢字進(jìn)行顯示。若評(píng)估不合格，根據(jù)顯示信息，重新采集指紋圖像信息，直到通過評(píng)估。系統(tǒng)工作流程圖如圖4 所示。
