摘　　要：介绍了文档图像处理技术的研究现状,分析了彩色文档图像不同于二值图像或灰度图像的主要特点,指出了彩色文档图像的压缩处理必须借助于现成的页面分割与分类成果,针对彩色文档图像的特点,改进PLA技术、ACR技术和GLR技术,在努力提高图像质量的前提下,对文档图像按区域类别的不同,选用有针对性的压缩方法,并对实现的技术路线进行了讨论。In this paper, current research situation of document image processing was first introduced. Then based on the analysis of the main feature differences between binary document image and color document image, this paper pointed out that it was necessary that the processing and compression of color document images should be accomplished by utilizing the research results of page segmentation and classification. The technical implementation path to the special interested region, which aimed at improving the quality of document image processing by improving the techniques on PLA, ACR, and GLR, and by selecting specific compression method for special region,was discussed.
