車牌定位－－－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)車牌水平位置,利用垂直投影法檢測(cè)車牌垂直位置。 7.區(qū)域裁剪,截取車牌圖像。

This a set of notes I put together for my Computer Architecture class in 1990. Students had a project in which they had to model a microprocessor architecture of their choice. They used these notes to learn VHDL. The notes cover the VHDL-87 version of the language. Not all of the language is covered (about 95％). You may use this booklet for your own personal learning purposes. You may not use it for profit (eg, selling copies of it, using it in a course for which people pay, etc). If you want to make use of it beyond these conditions, contact me and we can come to some arrangement.

本書第一部分講述的是傳統(tǒng)的網(wǎng)絡(luò)接口N e t B I O S、重定向器以及通過重定向器進(jìn)行的各類 網(wǎng)絡(luò)通信。盡管本書大部分內(nèi)容均圍繞Wi n s o c k編程這一主題展開，但是， A P I比起Wi n s o c k 來，仍然具有某些獨(dú)到之處
