Digital Watermark Method Based on NAM and Integer Wavelets
(0) This paper proposes a non-symmetry and anti-packing pattern representation model, which is short for the NAM color image representation method. It presents a new color image representation algorithm based on NAM and integer wavelets through the method of binary-bit plane decomposition of color images. The color image is divided into a grey image with r, g, b components. In this paper, an embedding strategyand examining the digital watermarking algorithm based on wavelet transformation is proposed. Digital watermarking is embedded into the middle frequency subband of the original image in the r, g, b domain. Experiments show that the methodis good at representing color images and experiments indicate that the algorithm operation is simple, storage space is small, effective resistance to different types of attack, as well with a strong theoretical approach and applicability.
