- W2971369400 abstract "With increasing development of information technology, electronic publishing is becoming more popular, so need for copyright protection has been increased. Digital watermarking is used to protect digital data from being altered. This paper presents an algorithm to embed fractal images in wavelet domain using LWT (Lifting Wavelet Transform). Fractal image is generated from Quadtree decomposition and converted into binary image. This binary image is used as watermark. Cover image is converted into RGB components and binary watermark is inserted into mid frequency bands of cover image to protect information from attackers. Watermark is implanted in the blue component of RGB image. The PSNR, SSIM, and NC values obtained in this research show that the method is imperceptible and robust against signal distortions such as contrast enhancement, gamma correction, image sharpening, Gaussian filter, etc." @default.
