In this paper

an ISS algorithm with adaptive parameters has been proposed. It takes into account the features of human visual system(HVS) and thus can limit the local distortion of the watermarked images. By doing this way

the watermarking scheme has better transparency and stronger robustness. Experimental results demonstrate that the proposed algorithm overcomes big local distortion existed in ISS scheme

and is robust enough against many kinds of image processing such as JPEG compression

noise filtering.
