Abstract: With the growth of new image technologies, copyright protection becomes an important issue to preserve digital images and video properties. In this paper, we propose an improved implementation of a blind object watermarking scheme for images and video streams. To make the watermark robust and perceptual invisible, we have used a two dimensional wavelet transform as a transformation domain for both image and watermark. We have also used an optimized quantization and replacement strategies within the insertion process. A hardware architecture is designed and tested in order to evaluate the performance of our proposed watermarking algorithm. This architecture has been implemented on the Altera Stratix II prototyping board.
