1.24位真彩色->256色灰度圖。 2.預處理:中值濾波。 3.二值化:用一個初始閾值T對圖像A進行二值化得到二值化圖像B。 初始閾值T的確定方法是:選擇閾值T=Gmax-(Gmax-Gmin)/3,Gmax和Gmin分別是最高、最低灰度值。 該閾值對不同牌照有一定的適應性,能夠保證背景基本被置為0,以突出牌照區域。 4.削弱背景干擾。對圖像B做簡單的相鄰像素灰度值相減,得到新的圖像G,即Gi,j=|Pi,j-Pi,j-1|i=0,1,…,439 j=0,1,…,639Gi,0=Pi,0,左邊緣直接賦值,不會影響整體效果。 5.用自定義模板進行中值濾波 區域灰度基本被賦值為0。考慮到文字是由許多短豎線組成,而背景噪聲有一大部分是孤立噪聲,用模板(1,1,1,1,1)T對G進行中值濾波,能夠得到除掉了大部分干擾的圖像C。 6.牌照搜索:利用水平投影法檢測車牌水平位置,利用垂直投影法檢測車牌垂直位置。 7.區域裁剪,截取車牌圖像。
