Chaotic Dynamic S Boxes Based Substitution Approach for Digital Images [PDF]
In this paper, we propose an image encryption algorithm based on the chaos, substitution boxes, nonlinear transformation in Galois field and Latin square. Initially, the dynamic S boxes are generated using Fisher Yates shuffle method and piece wise linear chaotic map.

Fracture toughness testing using photogrammetry and digital image correlation
Digital image correlation (DIC) is an optical technique commonly used for measuring displacement fields by tracking artificially applied random speckle patterns, which can sometimes be a problem for tracking small-scale displacements. DIC is particularly

A Chaotic Image Encryption Scheme Using Novel Geometric Block Permutation and Dynamic Substitution [PDF]
In this digital era, ensuring the security of digital data during transmission and storage is crucial. Digital data, particularly image data, needs to be protected against unauthorized access. To address this, this paper presents a novel image encryption scheme based on a confusion diffusion architecture.

Examining the Influence of Digital Phantom Models in Virtual Imaging Trials for Tomographic Breast Imaging [PDF]
Purpose: Digital phantoms are one of the key components of virtual imaging trials (VITs) that aim to assess and optimize new medical imaging systems and algorithms. However, these phantoms vary in their voxel resolution, appearance, and structural details.
