IMAGE WATERMARKING USING THE STEERABLE PYRAMID TRANSFORM

The protection of intellectual property rights became recently a pressing need especially with the rapid growth of transmission techniques. In this paper, we present as a copyright protection method, a non-blind watermarking technique based on the image content. We choose edges for watermark insertion. Our approach uses the steerable pyramid decomposition: the image is decomposed into a set of subbands and each one is individually marked. Many experiences performed with real images shows the good performance of the proposed method which is resistant to JPEG compression, additive noise and median filtering.
