档案图像和自然图像的实验对比分析

Analysis on the FeatureS of the Digital Document Image

得益于计算机技术和Internet的发展，越来越多的纸质档案被数码化而成为档案图像并在Intranet和Extranet上广泛应用，档案图像的数字图像处理要求也大量增加。在此背景下，本文细致分析了档案图像的固有特点和直方图特点，指出档案图像和自然图像在数字图像性能方面的迥然不同，为档案图像的进一步处理打下基础。

With the development of computer technology and Internet, more and more paper archives were digitalized to document images. Then more and more image processing requirements were increased with the document image system operating on Intranet and Extranet. Thus, for the purpose of further image processing, the document features included potential aspects and histograms were analyzed. The experiments show that there are different digital image characteristics between the document image and the natural image.
