To become involved in document imaging, you presumably already have a large collection of paper documents. These documents must be converted into electronic images in a process known as backfile conversion. According to one particularly practical article, this process involves the following five steps:(12) Document PreparationOrganize and discard old documents. ScanningPurchase an appropriate scanner for your documents. Autofeed scanners are a myth; hands-on feeding is a reality. IndexingCreate all potential identifiers, using current technology such as autoindexing, OCR, and bar codes. Where possible, use existing databases to retrieve additional information, such as employee information from an ID. Quality AssuranceManage the process carefully; conversion is tedious and difficult. Get it right the first time, because reprocessing is expensive. Image IntegrationYour goal is a system to handle daily throughput. Service bureaus may be appropriate for the backfile work while you focus on the future system. As part of the document conversion process, paper documents are scanned, and images are converted into electronic files and kept in large electronic filing cabinets.(13) The document images may be recognized by optical character recognition (OCR) software and converted into computer interpretable text, which can be indexed and searched. According to the news magazine Imaging World, "office workers spend 60% of the day dealing with paper documents and U.S. businesses continue to create over one billion pages of paper each day."(14) That's a lot of trees. The same article categorizes the imaging market into five components: ? image input ? image storage ? image management and processing ? image communications ? image output and display Let's examine three aspects of these components. First, the OCR part of the input component; second, text retrieval, part of the management and processing component; finally, the media issues that are part of the storage component.http://cache.baidu.com/c?word=%D3%D0%B9%D8%3B%BC%C6%CB%E3%BB%FA%3B%B5%C4%3B%D3%A2%CE%C4%3B%CE%C4%D5%C2&url=http%3A//zhidao%2Ebaidu%2Ecom/question/7770645%2Ehtml&p=8e6cc1019e904eac5c9fc4710f08&user=baiduhttp://www.baidu.com/s?wd=%D3%D0%B9%D8%BC%C6%CB%E3%BB%FA%B5%C4%D3%A2%CE%C4%CE%C4%D5%C2&cl=3自己去这里查吧,多得是哦!参考资料：在网上查的！本回答被网友采纳 |
