Title: STL Tutorial and Reference Guide: C++ Programming with the Standard Template Library (2nd Edition) Author: David R. Musser / Gillmer J. Derge / Atul Saini / Gilmer J. Derge Publisher: Addison-Wesley Page: 560 Edition: 2nd edition (March 27, 2001) Format: PDF Summary: The Standard Template Library was created as the first library of genetic algorithms and data structures, with four ideas in mind: generic programming, abstractness without loss of efficiency, the Von Neumann computation model, and value semantics. This guide provides a tutorial, a description of each element of the library, and sample applications. The expanded second edition includes new code examples and demonstrations of the use of STL in real-world C++ software development it reflects changes made to STL for the final ANSI/ISO C++ language standard.

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(xiàn)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。
