Abstract: This paper proposes creating new reversible marking technique. This originally based on indentifying parts of the image which are watermarked using two different Histogram Shifting (HS) modulations. One is Pixel Histogram shifting and other is Dynamic Prediction Error Histogram Shifting (DPEHS). This technique offers a very good compromise in terms of capacity and image quality preservation for medical image and natural image. The Prediction Error Histogram Shifting (DPEHS) can be combined with the expansion embedding (EE) modulation as well as pixel prediction.
Keywords: Dynamic Prediction Error Histogram Shifting (DPEHS), Expansion Embedding (EE), Histogram Shifting (HS), Pixel Histogram Shifting (PHS).
Scope of the Article: Regression and Prediction
