Design and Analysis of Efficient Blind Reversible Watermarking Technique
This paper proposes a blind reversible watermarking techniquewhich incorporates the histogram shifting in wavelet domain. The integer wavelet transform is used to transform the image into wavelet domain. The watermark data is embedded into the sub-band coefficients identified by just noticeable distortion (JND)of the transformed host image. To ensure the prohibition of pixel overflow and underf...
متن کاملEfficient Reversible Watermarking Technique with Contrast Enhancement for Color Images
In this paper histogram bin shifting based reversible data hiding algorithm for color images has been proposed. In this technique binary bits are embedded directly by addition and subtraction in two highest bin chosen and this process is repeated in modified histogram. A location map is generated by pre -processing to prevent the unnecessary overflow and underflow. All other pixels except two h...
متن کاملReversible Watermarking Technique using Histogram Shifting Modulations
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...
متن کاملReversible Picture Watermarking by Interpolation Technique
watermarking implant information into a digital signal like audio, Picture, or video. Reversible Picture watermarking can bring back the original picture without any distortion after the hidden data is extracted. In this paper, we present a novel reversible watermarking scheme using an interpolation procedure, which can embed a large amount of covert data into Pictures with imperceptible modifi...
متن کاملReversible Non-Blind Video Watermarking Based on Interlacing using 3-level DWT & Alpha Blending Technique
The growth of the Internet has frequently increased the availability of digital data such as text, audio, images and videos to the public. Digital watermarking is one of the important techniques to secure digital data in the field of authentication, copyright protection and security. The non-blind watermarking systems have a main problem that for extracting the watermark image from the watermar...
