摘要
模式識(shí)別就是通過(guò)計(jì)算機(jī)用數(shù)學(xué)技術(shù)方法來(lái)研究模式的自動(dòng)處理和識(shí)別。隨著計(jì)算機(jī)技術(shù)的發(fā)展，人類對(duì)模式識(shí)別技術(shù)提出了更高的要求。在我國(guó)如何將漢字方便、快速地輸入到計(jì)算機(jī)中已成為關(guān)系到計(jì)算機(jī)技術(shù)普及的關(guān)鍵問(wèn)題。特別是對(duì)于大量己有的印刷資料和手稿，計(jì)算機(jī)自動(dòng)識(shí)別輸入己成為必須研究的課題，所以漢字識(shí)別在文獻(xiàn)檢索、辦公自動(dòng)化、郵政系統(tǒng)、銀行票據(jù)處理等方面有著廣闊的應(yīng)用前景。
對(duì)手寫(xiě)漢字進(jìn)行識(shí)別，首先將漢字圖像進(jìn)行處理，抽取主要表達(dá)特征并將特征與漢字的代碼存儲(chǔ)在計(jì)算機(jī)中，這一過(guò)程叫做“訓(xùn)練”。識(shí)別過(guò)程就是將輸入的漢字圖像經(jīng)處理后與計(jì)算機(jī)中的所有字進(jìn)行比較，找出最相近的字就是識(shí)別結(jié)果，這一過(guò)程叫做“匹配”。
本文主要介紹了模式識(shí)別的基本原理和手寫(xiě)的10個(gè)漢字字符的識(shí)別系統(tǒng)的設(shè)計(jì)實(shí)現(xiàn)過(guò)程。第一章介紹了與模式識(shí)別有關(guān)的概念、描述方法、有關(guān)的數(shù)學(xué)運(yùn)算和此學(xué)科的發(fā)展?fàn)顩r。第二章分析了模式識(shí)別的過(guò)程、圖像文件的格式，并詳細(xì)介紹了BMP格式圖像的結(jié)構(gòu)；由于本文設(shè)計(jì)的識(shí)別系統(tǒng)是在VC++環(huán)境下開(kāi)發(fā)的，所以給出了CDib類的定義和功能介紹。第三章主要討論了分類器設(shè)計(jì)過(guò)程中的特征空間優(yōu)化設(shè)計(jì)問(wèn)題、分類器設(shè)計(jì)準(zhǔn)則、基本方法和判別函數(shù)的知識(shí)。第四章在前三章知識(shí)的基礎(chǔ)上，給出了模板匹配法識(shí)別圖像的原理，類GetFeature的功能及定義，識(shí)別系統(tǒng)設(shè)計(jì)的開(kāi)發(fā)流程及實(shí)現(xiàn)過(guò)程，并對(duì)實(shí)驗(yàn)結(jié)果做出簡(jiǎn)單的分析。

ABSTRACT
The pattern recognition researches how to treat with and recognize pattern automatically through computer with math arithmetic. Along with the development of computer technology, human need more advanced pattern recognition technology. In our country it is a key problem for computer technology’s popularization that how to input Chinese characters into computer fleetly and conveniently. Especially for large numbers of printed data and manuscript, the automatic recognition and input of Chinese characters becomes a stringent task, therefore the Chinese character recognition will have a broad application prospect on literature retrieval, office automation, postal service system, bank bill processing.
In order to recognize Chinese characters, the first task we have to do is feature extraction of a map, after that we have to store the feature in the computer. This process is called "the training". The second process is called “match”, This process compares the hand-written Chinese character’s feature and the stored features in the computer. 〖資料來(lái)源：畢業(yè)設(shè)計(jì)(論文)網(wǎng) WWW.56DOC.COM〗
This paper mainly introduces the basic principles of pattern recognition and the design、 realization process of ten hand-written Chinese characters recognition system. The first chapter mainly introduces the concepts related to the pattern recognition, the description method, the mathematics operation and this discipline’s development condition. The second chapter introduces the pattern recognition’s process, the picture format, especially the BMP form which is used in this paper. This article designs the recognition system under the VC IDE, therefore we introduce a CDib class’s definition and the functions. The third chapter mainly introduces characteristic space optimization design, the classification’s design criterion, the essential method and the knowledge about knowledge function. The fourth chapter produces the principle of template match recognition arithmetic, the class GetFeature’s definition and the functions, the recognition system’s design flow and the realization’s process, finally we produce the experimental result and the simple analysis. 〖資料來(lái)源：畢業(yè)設(shè)計(jì)(論文)網(wǎng) www.56doc.com〗
