INVISIBLE MULTIPLE WATERMARKING WITH MINIMUM DISTORTION USING DWT-DCT-CDMA
Journal Title: International Journal of Computer Science & Engineering Technology - Year 2012, Vol 3, Issue 8
Abstract
with the advent of digital media copyright protection is main concern. To protect copyright of images DWT DCT image watermarking is used. In this CDMA approach of embedding watermark is taken so that maximum number of watermarks can be embedded in original image to increase its authenticity. After embedding PSNR values are calculated at each watermark embedding and a table is constructed showing PSNR at each level. At the receiver end retrieval of watermark is done by correlation of original image.
