摘要
提出了一种基于欧拉数及HSV色彩空间的视频水印离散余弦变换(DCT)算法。在视频中选择欧拉数较小的帧,在HSV色彩空间亮度分量DCT中频系数中嵌入水印。该算法能实现盲嵌入、盲检测和盲提取,且健壮性强、透明性好,能经受噪声、滤波、剪切、压缩、帧插入及删除等图像、视频处理与攻击。
This paper presents a new DCT algorithm of video watermarking based on euler number and HSV. Less euler number frames of the video are chosen, value component of HSV is transformed by DCT, and the watermarking messages has been embedded into intermediate frequency of the DCT coefficient. Blind embedding, blind detection and blind extraction can be realized. The proposed algorithm is hidden, transparent and robust. It is proof against common image and video processing and attack, such as noise, filter, cut, compression, insert and erase etc.
