摘要： 提出了一种基于卷积码的空间域图像数字水印方法,通过将水印加于图像的LSB上,具有生成与检测方便、隐藏性好等特点。文章中给出了实验结果和攻击分析,表明这种方法对裁剪、Bit-complement和盐和胡椒噪声的攻击都有良好的性能。最后,还提出了几种未来可以进行的改进方案。

Abstract: The paper proposes a spacial digital watermarking method, which is based on convolutional encoding here. By hiding the watermark in the image's LSB, the paper makes it easy to generate or detect and difficult to feel the watermark. It also gives the result and the performance after the watermark being attacked. It shows that using convolutional encoding in spacial domain has good performance towards cutting, BIT-COMPLEMENT attack or salt & pepper noise. In the end, it proposes some potential ways to improve this proposed method .
