Abstract |
This paper suggest a latest reversible watermarking method. This originally identifies the part of the image using two different techniques .One is pixel Histogram Shifting and the other Dynamic Prediction Error Histogram Shifting. Histogram shifting modulation adaptively takes care of the local specificities of the image content. By applying it to the image prediction-errors and by considering their immediate neighborhood, the scheme we propose inserts data in textured areas where other methods fail to do so. This technique offers a very good compromise in terms of capacity and image quality preservation for medical images and natural images.
