Reversible watermarking method based on asymmetric-histogram shifting of prediction errors
This paper tries to provide a new perspective for the research of reversible watermarking based on histogram shifting of prediction errors. Instead of obtaining one prediction error for the current pixel, we calculate multiple prediction errors by designing a multi-prediction scheme. An asymmetric error histogram is then constructed by selecting the suitable one from these errors. Compared with...
متن کاملA New Reversible Watermarking Method Based on Histogram Shifting
This paper proposes a new histogram shifting-based reversible watermarking method. In contrast to other almost methods that need to use simultaneously the watermarked image and some image-dependent side information to restore the watermark and the original image, our method can do above restorations without any auxiliary information. Such methods are called free from side information. Our solut...
متن کاملReversible Watermarking Based on Optimal Dynamic Histogram Shifting
A new reversible watermarking scheme have been proposed for protecting the images of sensitive content. This scheme makes use of a classification process for identifying parts of the image that can be watermarked using two modulations. This classification is based on a reference image derived from the image itself aprediction ofit which has the property of being invariant to the watermark inser...
متن کاملReversible Watermarking based on Entropy Masking with Histogram Shifting
In this paper an improved method for reversible watermarking is proposed. This scheme is the combination of entropy masking and histogram. One first contribution is entropy masking which has three techniques. From three of them dwt is used for the watermarking. Entropy masking is also a human visual system’s characteristic, which rarely has been addressed in visual models. The second contributi...
متن کاملReversible Watermarking based on Histogram Shifting Modification:A Review
When we talk about the data communication or exchange of information from sender to receiver, the major concern is DATA. This (data) being of high importance, prone to various kinds of attacks. In order to protect it, data hiding techniques are used. Some of the data hiding techniques available are digital watermarking, steganography, etc. By digital watermarking, data is hidden in any type of ...
