Reversible steganographic method based on interpolation and genetic algorithm

Amine Benhfid
2020 International Journal of Advanced Trends in Computer Science and Engineering  
In this paper, a new reversible steganographic method based on the genetic algorithms (GA) combined with the interpolation by linear box-splines on the three directional mesh is proposed.  ...  These hypotheses were corroborated by intensive experimental results that were accomplished on a wide set of test images. We obtained a good trade-off between imperceptibility and capacity.  ...  Based on this interpolation method, a new reversible steganographic approach that hides the secret data in the error between the cover and the interpolated pixels is proposed.  ...

Steganography Based on Integer Wavelet Transform and Bicubic Interpolation

N. Ajeeshvali, B. Rajasekhar
2012 International Journal of Image Graphics and Signal Processing  
Bicubic interpolation causes overshoot, which increases acutance (apparent sharpness). The Bicubic algorithm is frequently used for scaling images and video for display.  ...  Steganography is the art and science of hiding information in unremarkable cover media so as not to observe any suspicion.  ...  Data hiding techniques The most popular hiding techniques are spatial domain and transform domain based techniques.  ...
