A 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...

متن کاملDWT Based Robust Technique of Watermarking Applied on Digital Images
399 Abstract:Digital Watermarking is a process of embedding unnoticeable signal in an image in the form of text and image in such a way that intruder is no able to trace the signal to enhance Copyright Protection. This Paper presents an efficient Watermarking Technique for Digital Media Content Protection and Copyright Protection. Watermarking is a technique to embed hidden and unnoticeable sig...
