%X Of all popular algorithms of transform domain, found most transformations to be orthogonal transformations (such as DCT and DWT). Selected Walsh transformation with excellent performance by studying Walsh function system. Finally, proposed a digital watermarking algorithm based on Walsh transformation. Experimental results show that the simple algorithm is good at perceptual transparency as well as robustness against noise and JPEG compression.
