Watermarking Algorithm about Videos Based on Watson Model
Haixia Chen · Journal of Fuqing Branch of Fujian Normal University · 2011
This paper proposed a new watermarking algorithm about videos based on Watson Model.First,we pick up some key frames of the videos and copy them as duplications.Second,we transform frames and their copies from RGB into YCrCB color space.Then,we embed watermark into the mid frequency band of the key frames and copies after suitable DCT operation.At last,we replace frames and copies into the formal video together.
