【正文】 Abstract II Handwritten Digit Recognition System Students： Teacher： Abstract: With the rapid development of science and technology, in zip code, statistics, reports, financial statements, Bank bills dealing with a large number of characters, such as information recorded occasions, handwritten digit recognition system of requirement has bee stronger and stronger, how easily and quickly the number entered in the puter has bee a key issue relates to the popularization of puter technology. This article design implementation has a based on Matlab software of handwriting body digital recognition system, used module of design method, write has camera entered, and directly read pictures, and write Board entered three a module, using camera, tools, will to text form exists of handwriting body digital entered into puter, pleted on handwriting body digital pictures of collection, and design has a handwriting digital recognition method, on handwriting body digital image for pretreatment, and structure features extraction, and classification recognition, eventually to text form output digital, to implementation handwriting body digital of recognition. Key words: Pretreatment, structure feature extraction, classification and recognition, handwritten digit recognition.目錄 III 目 錄 第一章 引言 .....................................................................................................................1 課題背景 ..................................................................................................................1 課題研究目的及意義 ..............................................................................................1 手寫體數(shù)字識(shí)別的研究目的 ............................................................................1 手寫體數(shù)字識(shí)別的研究意義 ............................................................................2 課題研究現(xiàn)狀及發(fā)展趨勢(shì) ......................................................................................2 課題整體結(jié)構(gòu) ..........................................................................................................3 課題難點(diǎn)分析 ..........................................................................................................4 第二章 開發(fā)運(yùn)行環(huán)境 .....................................................................................................5 系統(tǒng)開發(fā)環(huán)境和運(yùn)行環(huán)境 ......................................................................................5 開發(fā)工具介紹 ..........................................................................................................5 硬件部分介紹 ....................................................................................................5 軟件部分介紹 ....................................................................................................6 第三章 手寫體數(shù)字識(shí)別系統(tǒng)構(gòu)成及原理 .....................................................................8 圖像處理基礎(chǔ)知識(shí) ..................................................................................................8 手寫體數(shù)字識(shí)別系統(tǒng)構(gòu)成 ....................................................................................10 手寫體數(shù)字識(shí)別系統(tǒng)原理 ....................................................................................10 預(yù)處理 ...............................................................................................................10 圖像分割 ...........................................................................................................14 特 征提取 ...........................................................................................................14 分類識(shí)別 ...........................................................................................................15 第四章 手寫體數(shù)字識(shí)別系統(tǒng)設(shè)計(jì)分析 .......................................................................16 程序主界面 ............................................................................................................16 基準(zhǔn)庫的選擇與建立 ............................................................................................18 目錄 IV 手寫體數(shù)字識(shí)別系統(tǒng)設(shè)計(jì) ....................................................................................19 攝像頭輸入模塊的設(shè)計(jì) ...................................................................................19 直接讀圖模塊的設(shè)計(jì) .......................................................................................21 寫字板輸入模塊的設(shè)計(jì) ...................................................................................22 第五章 系統(tǒng)性能評(píng)價(jià)及實(shí)驗(yàn)結(jié)果分析 .......................................................................25 識(shí)別系統(tǒng)性能的評(píng)價(jià) ............................................................................................25 實(shí)驗(yàn)結(jié)果分析 ........................................................................................................25 第六章 結(jié)論 ...................................................................................................................27 畢業(yè)設(shè)計(jì)總結(jié) ........................................................................................................27 課題前景與展望 ....................................................................................................27 致 謝 ...............................................................................................................................29 參考文獻(xiàn) .........................................................................................................................30 附 錄 ...............................................................................................................................31 附 識(shí)別部分主程序 ...............................................................................................31 附 創(chuàng)建模板部分函數(shù) ...........................................................................................32 附 切割圖片部 分函數(shù) ...........................................................................................33 附 輸出圖片部分函數(shù) ...........................................................................................34 第一章 引言 1
