标准摘要
[中文适用范围]: 本建议书 | 国际标准 1 定义了用于编码二值图像和图像集(由多页组成的文档)的方法。该方法尤其适用于由文本和抖动(半色调)数据组成的二值图像。定义的方法允许无损(位保留)编码、有损编码和逐行编码。在逐行编码中,第一幅图像是有损的;后续图像可能是有损的,也可能是无损的。本建议书 | 国际标准还定义了用于封装已编码二值图像数据的文件格式。 [外文原描述]: This Recommendation | International Standard defines methods for coding bi-level images and sets of images (documents consisting of multiple pages). It is particularly suitable for bi-level images consisting of text and dithered (halftone) data. The methods defined permit lossless (bit-preserving) coding, lossy coding, and progressive coding. In progressive coding, the first image is lossy; subsequent images may be lossy or lossless. This Recommendation | International Standard also defines file formats to enclose the coded bi-level image data.
