Data and image security is one of the most important aspects of information storage as well
as the massive and still expanding internet. The frequent use of images of various types …

This paper discusses different nonlinear techniques for removing noise from images; ie,
image denoising. These techniques differ in terms of algorithm design, purpose …

In cryptography, the previous research generally appears ambiguous and complex to the
novice researcher due to the use of complex mathematical equations and rules of …

A new algorithm is presented for lossless image encryption using a private key. The image is
regarded as a stream of bytes, and grouped into variable-length blocks whose sizes depend …

This new algorithm performs lossless image encryption by combining variable-length key-
dependent XOR encryption with S-box substitution. This algorithm was implemented and …

The metrics or measures used in evaluating image quality usually serve applications that
aim at enhancing image appearance or at preventing the image quality from degrading after …

With the continued evolution of three dimensional (3D) object presentation and usage, the
security of such objects has become an increasingly desirable research area. Previous …

This chapter proposes a new multiple-image encryption algorithm based on spectral fusion
of watermarked images and new chaotic generators. Logistic-May (LM), May-Gaussian …

In order to adapt to the new changes in the network era, to solve the problems of the high
cost of navigation radar equipment, the high cost of navigation teaching and training and …

This paper proposes a new multiple-image encryption algorithm based on spectral fusion of
images and new chaotic generators. Logistic-May (LM), May-Gaussian (MG) and Gaussian …
