A digital watermarking algorithm in binary text image: Because of the weak information hiding immunity of binary text image, many watermarking methods based on gray or color images are useless.
改进的二值文本图像水印算法：由于二值图像信息隐藏免疫力差，绝大多数基于灰度或彩色图像的水印算法不再适用。
The image has been divided into several sections, the gray value of the largest, second and third of each section has been embeded watermarking by module 2.
将图像划分为若干节，对每节最大、第二、第三等三个灰度值分别采用模2法嵌入水印。
For traditional watermarking techniques based on fractal coding, watermarking format is limited to binary sequence 0, 1, thus incapable of gray-scale image embedding.
传统的基于分形编码的水印技术一般嵌入0,1序列，没有实现灰度图像嵌入。
