A robust video watermarking technique in the spatial domain
We present a scheme for robust watermark insertion into video sequences. The proposed approach works in the uncompressed image domain, and it is robust against a large set of possible attacks. It has been developed for two principle applications: copyright protection and invisible embedding of indexing information. The proposed scheme has been tested and the results show that a robust watermark can be embedded in video sequences, and extracted after different attacks, in particular MPEG compression and geometrical attacks like cropping and resizing. We also compared two different error correcting codes used to improve robustness: convolutional and turbo codes.
