Robust watermarking scheme based on the JPEG2000 standard
In this paper an empirical evaluation of the lossy compression properties of the JPEG2000 standard for watermarking and fingerprinting purposes is performed. The JPEG2000 standard is used as a basic tool for determining both how and where the embedded watermark should be placed in the image. The original image is slightly modified in order to generate a similar image (but indistinguishable by t...

The JPEG2000 standard is used as a basic tool for determining both how and where the embedded watermark should be placed in the image. The original image is slightly modified in order to generate a similar image (indistinguishable by the observer), and the m...
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...
