Abstract

Two robust spatial-domain watermarking algorithms for image copyright protection are described in this paper. The first one is robust against compression, filtering and cropping. Like all published crop-proof algorithms, the one proposed here requires the original image for mark recovery. Robustness against compression and filtering is obtained by using the JPEG algorithm to decide on mark location and magnitude; robustness against cropping is achieved through a repetition code. The second watermarking algorithm uses visual components and is robust against compression, filtering, scaling and moderate rotations.
