Watermarking schemes have been extensively discussed and developed recently. People are usually facing the dilemma of two factors, robustness and transparency. To achieve these requirements, embedding the watermark message in the transform domain or the spatial domain is usually considered. In this paper, we will propose a blind image watermarking scheme based on vector quantization. By exploiting a modified binary tree splitting method, a stable codebook could be generated so that the watermark message could be novelly embedded and survive the JPEG compression and the Gaussian noise addition. The embedded message could be extracted without referring the host image. It makes the scheme more practical.
