摘要: 提出了一种新的基于一维DFT和Radon变换的视频水印算法,对视频帧进行一维DFT变换,选择频率最高的帧作为嵌入水印的帧,并对该帧进行Radon变换后进行水印的嵌入和抽取。本算法通过三种不同比特率进行了H.264压缩攻击,进行了旋转、平移、缩放的几何变换攻击,同时进行了帧丢失、帧变换、滤波和加噪攻击实验,结果本文算法对上述攻击具有很好的鲁棒性。本算法最重要的优点是具有简单性和实用性。

Abstract:

A new video watermarking algorithm based on the 1D DFT (one-dimensional discrete Fourier transform) and Radon transform was proposed in this paper. The 1D DFT for a video sequence generates an ideal domain. The frames with highest frequency were chosen to embed the watermark in the Radon transform domain. The performance of the proposed algorithm is evaluated by video compression standard H.264 with three different bit rates; geometric attacks such as rotation, translation, and aspectratio; and other attacks like frame drop, frame swap, spatial filtering, noise addition, lighting were conducted. The results show that the algorithm is robust to the attack. One of the most important advantages of this video watermarking algorithm is its simplicity and practicality.
