印刷英文字之手持式藍牙即時辨識系統

文件分析與辨識之研究行之已久，應用十分廣泛，在數位化過程中扮演十分重要的角色。最常用的方法是採用體積龐大的桌上型掃瞄器，經過耗時的文件掃瞄等待，透過有線連接將影像資料傳送給電腦端的套裝應用軟體來進行處理、分析、辨識以及備份。為了增進這個應用的效率與方便性，本論文提出一種低成本又便於攜帶的英文平面印刷刊物文章段落之取像架構，然後導入快速辨識之演算法於數位信號處理器內實現，感興趣範圍的辨識結果則顯示在液晶螢幕上，並透過藍牙資料傳輸的技術，將辨識結果同步上傳至電腦端。這些辨識結果的資料可以提供給電腦端未來相關應用之使用。大量之實驗結果顯示本論文所提之架構可快速且正確辨識不同之英文平面印刷刊物文章段落。

The research of document analysis and recognition is put into practice for long time and applied popularly. It plays the leading role in the digitalization process. The commonest way is that it makes use of a flatbed scanner with big size via a long waiting of document scanning and then transmits the image data to PC (Personal Computer) simultaneously via a wired connection. The transmitted images are used in advanced processing, analysis, recognition as well as back-up of a suite of application program. In order to improve the efficiency and convenience of the application, the thesis proposes a low cost and portable opto-mechanism to grab the article or the paragraph of English machine printed publication. Furthermore, the algorithms of fast recognition are implemented on DSP (Digital Signal Processer). The recognition results of ROI (Region of Interest) are not only displayed on a LCD (Liquid Crystal Display) monitor but also transmitted to PC via data transmission technology of Bluetooth. These data of the recognition results can provide PC with the usage of relevant applications in the future. Finally, an amount of experimental results verify that the proposed recognition system can rapidly and correctly recognize the article or the paragraph of English machine printed publication.
