Abstract

In this chapter, two dual watermarking techniques are discussed. Both of these methods are based on extracting features from an image and using the features to generate watermarks. The watermarking techniques discussed in this chapter are based on a combination of image features and forward error correction codes. It is shown how the ability of tolerance to modifications, location of modified positions and (partial) reconstruction of image is achieved through the discussed method. Simulation results are presented for different channels and using different codes.
