  A Hybrid BPS-DCT Based Digital Image Watermarking Technique

  By Dr. Priyanka, Sandeep garg

  Abstract: In this paper a hybrid algorithm using Bit Plane Slicing (BPS) and Discrete Cosine Transform (DCT) for digital image watermarking is proposed. There are two main requirements for digital image watermarking: imperceptibility and robustness. Imperceptibility is measured by Peak Signal to Noise Ratio and robustness is obtained by correlation between original and extracted watermark image. In this algorithm an image and watermark is first sliced into its bit planes using …
