Definition
Video watermarking refers to embedding watermarks in a video sequence in order to protect the video from illegal copying and identify manipulations.
A variety of robust and fragile video watermarking methods have been proposed to solve the illegal copying and proof of ownership problems as well as to identify manipulations. Although a number of broad claims have been made in the field of robustness of various digital watermarking methods, it is still difficult to handle combined or non-linear geometric transformations. The methods can be divided into techniques working on compressed or uncompressed data. In particular video watermarking is based in general on the following concepts to hide a watermark by modifying some of its characteristics:
- 1.
Spatial domain approach, also called native domain: embedding and detection are performed on spatial pixels values (luminance, chrominance, color space) or on the overall video frame characteristic
- 2....
