Abstract :
An adaptive watermarking technique based on gray-level digital watermarks is proposed. By still image decomposition technique, a gray-level digital watermark is decomposed into a series of binary digital images. The decomposed products can be used as usual two-dimensional binary digital watermarks. Experimental results show that the proposed technique is robust to attacks such as Joint Photographic Expects Group (JPEG) lossy compression
