基于TWAIN标准的文字图像采集方法研究

在文字识别过程中,文字图像采集是重要的一步,为了能够高效、高质量地从外接物理设备采集图像并直接进行处理,文中介绍了TWAIN的基本原理和工作过程,说明了TWAIN的应用前景及TWAIN开发扫描仪驱动程序的优势,并基于TWAIN运用VC++实现了在扫描仪上对文字采集的应用。实验结果表明,应用TWAIN标准所开发的程序能够达到设计的要求。

Study of TWAIN-based Character-Image Collection

In the process of character recognition,word-image collection is a very important step.In order to collect images efficiently with a good quality from external physical equipment and process them directly,this paper introduces the basic principles and working process of TWAIN,describes the wide application prospects of TWAIN and the advantages of using TWAIN to develop the scanner driver.The VC++ program is used to achieve the collection of character images on the scanner based on TWAIN.The experimental res...
