This project attempts to implement a Database using B+Tree. The project has developed a DATABASE SYSTEM with lesser memory consumption. Its API includes simple SQL Statements and the output is displayed on the screen. Certain applications for which several features of existing databases like concurrency control, transaction management, security features are not enabled. B+Trees can be used as an index for factor access to the data. Help facility is provided to know the syntax of SQL Statements.

1.24位真彩色->256色灰度圖。 2.預(yù)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(yīng)性,能夠保證背景基本被置為0,以突出牌照區(qū)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(qū)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(qū)域裁剪,截取車牌圖像。
