Reversible Image Watermarking for Health Informatics Systems Using Distortion Compensation in Wavelet Domain

Understand

Reversible image watermarking guaranties restoration of both original cover and watermark logo from the watermarked image.

• Capacity and distortion of the image under reversible watermarking are two important parameters.
• In this study a reversible watermarking is investigated with focusing on increasing the embedding capacity and reducing the distortion in medical images.
• Integer wavelet transform is used for embedding where in each iteration, one watermark bit is embedded in one transform coefficient.
