Abstract
Digital watermarking of digital images allow authentication of ownership and protection of intellectual property. We consider an algorithm wherein a luminance channel modulated watermark is embedded in the blue channel of a color image. The blue channel image is decomposed via a wavelet transform, and the embedding strength is varied depending on the resolution band. The resolution band weighting improves the algorithms' watermark recovery performance when distortion is introduced due to lossy compression.
