【摘要】 二值图像存储简单、结构紧嫡的独特优势使得二值图像在数据传真、文字条码识别和数字签名中得到了广泛的应用,也正是由于这个特点使得彩色、灰度图像的信息隐藏技术不能直接应用于二值图像信息隐藏中。总结概述了近年来二值图像的一些研究成果,并对这些研究成果的鲁棒性和隐藏容量等问题做了一个简要比较与讨论。更多还原

【Abstract】 While a variety of information hiding techniques are proposed for digital color and grayscale images, not all of them can be directly applied to binary images. A white_black image is lack of gray or color information to hold secret, arbitrarily changing pixel values on a binary image causes very noticeable artifacts.To present an summary and overview of recent developments on binary image information hiding, and discuss some important issues of those techniques such as robustness and data hiding capacity.更多还原
