Abstract

In this paper, a new image watermarking scheme is proposed that a watermark image is inserted into an original image and then reconstructed in frequency domain, after Hadamard-Walsh matrix is added to the watermark image using direct matrix-spread spectrum method. Visually recognizable pattern (mark, logo, symbol, stamping or signature) is used as a watermark image. In order to estimate the degradation of watermarked image quality, PSNR (Peak Signal to Noise Ratio) is calculated. For the robustness of watermark to protect an attack from the outside, the reconstructive rate is obtained. As a result of application to various standard images, image quality is less degraded as PSNR of 93.2dB. It is also observed that the reconstructive rate is no less than 78.1% in JPEG lossy compression, and under an image transformation and impulse noise, the watermark image can be effectively reconstructed.
