Robust Reversible Watermarking via Invariant Image Classification and DHS
Abstract: In this paper a new reversible watermarking scheme is proposed based on Dynamic Histogram Shifting (DHS). It adaptively takes care of the local specicities of the image content. Further a reference image is derived which is a copy of image itself. This reference image is invariant to the watermark insertion process. For identifying parts of the image that can be watermarked; Classication process is used. Further; Embedder and Extractor both use same reference image. Hence synchronisation exists between embedder and extractor for message extraction and image reconstruction. For sensitive images like medical or military images; our scheme can insert more data with lower distortion than other methods.
