車(chē)牌定位－－－VC++源代碼程序 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(gè)初始閾值T對(duì)圖像A進(jìn)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(duì)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(duì)圖像B做簡(jiǎn)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(huì)影響整體效果。 5.用自定義模板進(jìn)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(duì)G進(jìn)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(cè)車(chē)牌水平位置,利用垂直投影法檢測(cè)車(chē)牌垂直位置。 7.區(qū)域裁剪,截取車(chē)牌圖像。

JavaTV Program source code Need to play Windows Media files and streams, mpeg4 video or DVDs in java? Access WDM capture devices? Control a firewire DVCam? Then maybe this can help you. dsj is an ongoing project to provide a java wrapper around Microsoft s DirectShow API. It offers a set of high level classes that give java easy access to functionality widely missed by java programmers and also lets you dive deeper into the interiors of Windows core api for 2D media. On the java side dsj tries to keep things open as possible - you may use it standalone or let it feed data into JMF or other APIs.
