海明码在视频水印中的应用

Application of R.Hamming Redundancy Code in Video Watermark

通过分析海明码的实现原理,设计一个基于海明码的视频水印模型,并对该模型进行程序验证,实验结果表明:基于海明码的视频水印方案能够有效提高水印的可恢复性、顽健性、可升级性、适用性,但对视频画质有一定的影响。

By analyzing the realization principle of R.Hamming redundancy code, the paper designs a video watermark model based on R.Hamming redundancy code, and then by computer programming verifies the model.Experimental results shows that video watermark based on R.Hamming redundancy code could effectively improve recoversbility、robustness,scalability and applicability of watermark, but would have a certain impact on video quality.
