The method presented here is based on the discrete Fourier transform (DFT) of three dimensional chunks of video scene, in contrast with previous works on video watermarking where

Averaging attack consists of the local averaging of consecutive frames in order to cancel the watermark.. This attack works well for schemes which embed random independent marks

Black level clamping, often referred to as DC restoration is accomplished by applying a back porch clamp signal to the clamp gate input pin (pin 14).. The clamp comparator is

This paper proposes a new video watermarking scheme based on a hierarchical motion analysis, that is robust against classical video processing (filtering, lossy compression...)..

The last trend basically considers a video stream as some data compressed according to a specific video compression standard and the characteristics of such a standard can be used

Check the bare performance of the underlying still image watermarking algo- rithm with respect to capacity/robustness when the watermarked texture image is directly used for

The last term in (7) points out that, at this point, some background pixels may have not been estimated. In this case, the pixel values from the original video frame F t are
