指紋灰度圖像的前、背景分離
用點(diǎn)方向圖表示所述隔點(diǎn)原始指紋灰度圖像中每一像素點(diǎn)處的局部紋理走向，具體如下：
指紋圖像是由局部平行的脊線和谷線構(gòu)成的一種方向模式。通過指紋圖像點(diǎn)方向圖計(jì)算，可將指紋圖像中的各個(gè)圖像塊劃分為前景塊或背景塊。采用7×7 模板，基準(zhǔn)點(diǎn)位于模板中心，從水平位置開始每隔π/4 確定一個(gè)方向，定義I=1，2，3，4，對(duì)應(yīng)0，π/4，2π/4，3π/4，π 四個(gè)方向。按公式（1）計(jì)算各個(gè)方向的灰度變化DI，比較DI，找到最小值，就代表該點(diǎn)的方向，見公式（1）：
式中，是沿I方向上點(diǎn)的灰度均值，f1（ik ， jk） 是I方向上點(diǎn)的灰度值。
