A subsampling based watermarking scheme has been investigated for digital images in this study. The algorithm utilizes the wavelet multi-resolutional structure and subsamples the individual subband coefficients in order to embed the watermark information respectively. The extracting procedure reverses the embedding operations without the reference of the original image and provides a better copyright protection scheme. Compared with the similar approach by discrete cosine transform based approach, the wavelet based algorithm apparently preserves superior image quality and robustness under various attacks.
