Region based interpolation error expansion algorithm for reversible image watermarking
Proposed algorithm is a new reversible image watermarking algorithm based on interpolation error expansion. In the data extraction, original image can be obtained from watermarked image in a distortionless manner. Watermarking algorithm embeds data adaptively into the image. Spatial correlation has been exploited effectively by using image interpolation algorithm. Image quality is preserved by proposed pixel selection algorithm.
