This thesis explains the necessity of the character recognition technology of the computer at first, describe the meaning in which the handwritten numeral discerns ; pretreatment technology of handwritten numeral recognition, including two value, line segmentation, word segmentation smooth, removing noising, standardization and thinning are discussed two value concretely discusses whole threshold value, some threshold value, dynamic threshold value and utilize space information to carry on threshold, which are several kinds of common method of choosing threshold value, especially utilize space information to carry on threshold value is describe in detail ; adopting to the foundation of thinning based on mathematics morphology, thinning algorithm of serials same and thinning algorithm of protecting shape are discussed ; afterwards, according to principle ' s diagram of the on - line character recognition, by analyzing the structure feature of the handwritten numeral, this thesis has proposed the online recognition te chnology of the free handwritten numeral based on the stroke feature and the online recognition technology of the free handwritten numeral based on the multistage classifying device. detail narrated noise removing, stroke characteristic definition and discernment, distance criterion of whole word match ; then under the foundation of handwritten numeral segmentation, off - line handwritten numeral recognition is researched. especially minimum distance classifying device, tree classifying device and adaptive resonance ( art ) network classifying device is discussed at the same time, believes degree analyses are introduced to integrate a lot of classifying devices ; at the end, the typical application of the handwritten numeral recognition was briefly narrated, its application in extensive data statistics, financial affairs, tax, finance and mail sorting have been explored
二值化時對整體閾值二值化、局部閾值二值化、動態閾值二值化和利用空間信息進行閾值選取幾種常用的閾值選取方法進行討論，特別對利用空間信息進行閾值選取進行了詳細論述；在對通過對基於數學形態學的細化的基礎上，討論序貫同倫形態細化演算法和保形的快速形態細化演算法；然後依據聯機字元識別原理框圖，分析了手寫數字的結構特點，提出了基於筆劃特徵的任意手寫數字在線識別技術和基於多級分類器任意手寫數字在線識別技術，對其中涉及的筆劃識別前的噪聲處理、筆劃間特徵量的定義及識別、整字匹配的距離準則進行了詳細敘述；繼而在對手寫數字的分割的基礎下對脫機手寫數字識別進行了研究，對基於最小距離分類器字元識別、基於樹分類器的字元識別、基於自適應共振（ art ）網路的字元識別分別進行了詳細討論，並引入置信度分析將多個分類器進行了混合集成；最後簡單闡述了手寫數字識別的典型應用，對其在大規模數據統計、財務、稅務、金融及郵件分揀中的應用進行了探索。With the rapid development of wireless communication technology and computer technology ， people wish to get reliable data communication service any time and any where. traditional network can not supply communication service if the whole network need to move because the network devices are fixed by wires and can not move. so, ad hoc network comes. it can provide mobile data communication service compared with traditional network. ad hoc is a network with plat structure and all the nodes is equal. all the nodes need provide relay. but not all the nodes will provide relay and the performance of plat structure is poor in large scale. so the wireless mobile self - organized network adopts a two - level structure by referencing the cell mobile communication system. wmsn uses wireless routers to construct network. it can provide wireless access, relay services to users
考慮到不是所有的站點都願意提供中繼服務及平面結構的局限性（在網路規模較大時性能會很差） ，本課題的無線移動自組織網路參考了蜂窩移動通信系統的特點，是一種具有兩級結構的網路。使用專門的無線設備? ? 「無線路由器」構成具有用戶無線接入、無線組網和路由功能的無線互連網路，為移動用戶提供無線接入、路由和中繼服務。 ieee802 . 11b可以提供很高的通信速率，可以提供很好的接入性能，並且支持ieee802 . 11b協議的設備正成普及的態勢，因此成為我們所選擇的鏈路層協議。
