A robust video watermarking technique in the spatial domain

In this paper we present a scheme for robust watermarking insertion on 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 code used to improve robustness: convolutional and turbo codes.
