智能手机空间域数字水印算法

A digital watermarking algorithm in spatial domain for smart phones

将彩色图像分为三个色位面,分别嵌入按一定规律分块重新组织的水印信息,使水印图像能够均匀地嵌入在图像中。提取水印后,将水印分块,取得带有相同信息的水印子块,并利用多数原则判定子块各像素的值,得出最终水印信息。

The color image is divided into three color planes and then embedded into re-organized watermark information respectively with some rules,to make the watermark be evenly distributed in the image.After being extracted,the watermark is divided into sub-blocks.The sub-blocks with same information are obtained to get the final watermark by determining the pixel value by means of majority rule.
