By still image compression coding technique, the color digital watermark is encoded into a series of binary ID Numbers for watermarking.
利用静态图像的压缩编码技术，将彩色数字水印编码为一系列二值id数字，以实现水印的嵌入。
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。
Gray image about skin probability is processed by threshold. According to the color of skin, image containing faces is segmented, and the binary image can be got based on skin-color.
本文将改进的微粒群算法应用于人脸检测的预处理中，对皮肤概率灰度图像进行阈值化处理，依据肤色分割人脸图像，得到基于肤色的二值图像。
Firstly, the color image is coarsely segmented into several binary images, which is accomplished based on the analysis of the histogram of the H component of the HSI color model.
