A Gray Scale High Quality Digital Image Watermarking using Equal Pixel Value difference Method (EPVD)
Due to growth of Internet and multimedia technologies in today's life, it made easy to copy and distribution of any document without any owner's consent. Watermarking is a process of concealing the digital information in a document for providing the ownership on his/her document. To increase security of ownership of a document and to improve quality of indistinguishable watermarked im...
متن کاملLsb Based Digital Image Watermarking For Gray Scale Image
In recent years, internet revolution resulted in an explosive growth in multimedia applications. The rapid advancement of internet has made it easier to send the data/image accurate and faster to the destination. Besides this, it is easier to modify and misuse the valuable information through hacking at the same time. Digital watermarking is one of the proposed solutions for copyright protectio...
متن کاملPixel Value Adjustment for Digital Watermarking Using Uniform Color Space
In this chapter, we propose a pixel adjustment procedure for digital watermarking methods using uniform color space. Many digital watermarking methods use uniform color space due to the convenience of controlling image quality (Yoshiura & Echizen, 2006). However, there is the problem that watermarked RGB integer pixel values in such methods are not quite corresponding to the watermarked real-nu...

Keywords: Digital image watermarking Human visual system GA-BPN Hybrid intelligent system Robustness Discrete wavelet domain Peak-signal-to-noise ratio Normalized cross–correlation a b s t r a c t In this paper, a novel watermarking scheme is proposed by embedding a binary watermark into gray-scale images using a hybrid GA-BPN intelligent network. HVS characteristics of the images in DCT domain...
متن کاملA Robust Digital Image Watermarking Scheme Based on DWT
In this paper a wavelet-based logo watermarking scheme is presented. The logo watermark is embedded into all sub-blocks of the LLn sub-band of the transformed host image, using quantization technique. Extracted logos from all sub-blocks are merged to make the extracted watermark from distorted watermarked image. Knowing the quantization step-size, dimensions of logo and the level of wavelet tra...
