Three-dimensional histogram shifting for reversible data hiding

Multimedia Systems, 2016
Histogram shifting is an important method of reversible data hiding. However, every pixel, difference, or prediction-error is respectively changed to hide a data bit in the traditional histogram shifting, which constrains the capacity-distortion embedding performance.

Secure Reversible Data Hiding Using Block-Wise Histogram Shifting [PDF]

Electronics (Switzerland), 2023
Reversible data hiding (RDH) techniques recover the original cover image after data extraction. Thus, they have gained popularity in e-healthcare, law forensics, and military applications.

Reversible watermarking method based on asymmetric-histogram shifting of prediction errors [PDF]

Journal of Systems and Software, 2013
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 ...

Projection-histograms for mean-shift tracking

2010 IEEE International Conference on Image Processing, 2010
This paper proposes an extension to the mean shift tracking by using XY projection-histograms to medel the object. More than providing statistical information about the target to track, they embed information about the spatial arrangement of pixels. This approach, without any complexity increase, provides a better robustness and quality of the tracking.

Histogram Shift Steganography: A Technique to Thwart Histogram Based Steganalysis

2009 Second International Workshop on Computer Science and Engineering, 2009
We present an image steganographic technique to preserve the first-order and the second-order statistics of the host image. Experimental results show that the proposed method can preserve the image quality and also resists typical statistical analysis based attacks.

Reversible watermarking based on generalized histogram shifting

2011 18th IEEE International Conference on Image Processing, 2011
This paper proposes a generalization of the well-known histogram shifting method for reversible watermarking. Binary watermark source is converted into a non-binary source that produces symbols from an alphabet of n (n>2) symbols. A technique similar to that of generalized least significant bit (GLSB) is used to transform watermark; therefore ...

Reversible data hiding based on two-dimensional histogram and generalized histogram shifting

2014 IEEE International Conference on Image Processing (ICIP), 2014
In this paper, we propose a reversible data hiding (RDH) method based on a two-dimensional (2D) histogram and generalized histogram shifting (GHS). First, a cover image is decomposed into wavelet subbands using the integer-to-integer wavelet transform (I2I-WT).
