视频解码中的水印算法研究

An Research of Watermarking Algorithm in Vedio Decoding

提出视频解码过程中一种水印算法的实现过程,该算法根据视频图像解码过程的信息,对每一个像素系列计算可信度因子,据此完成视频图像的准确性和可靠性验证,这种方法不改变水印嵌入的条件,通过引入的可信度因子提高系统检测验证信息的精确度。

In this paper a vedio watermarking detection algorithm is introduced in detail. The information in the process of vedio decoding is utilized for calculating the confidence factor of each image. This improved algorithm can further increase the precision of watermarking detection compared to the traditional algorithm.
