Images serve as a valuable information carrier for their properties of visualization and
holding a large amount of messages. This paper presents a novel chaos-based encryption …

Many holistic image encryption schemes have been proposed in recent decades that
achieve a certain security level. However, considering the actual application environment …

With the modernization of biomedical image equipment and image processing technology,
the amount of medical image data increases rapidly. These medical images need to be …

This paper proposes a novel chaotic block image encryption algorithm based on deep
convolutional generative adversarial networks (DCGANs), quaternions, an improved Feistel …

Since the COVID-19 pandemic, telemedicine or non-face-to-face medicine has increased
significantly. In practice, various types of medical images are essential to achieve effective …

In order to satisfy the requirements of high quality and security during image transmission
and storage, this paper proposes an image lossless compression encryption algorithm …

In today's information society, image encryption technology is crucial to protecting Internet
security. However, traditional image encryption algorithms have problems such as …

A hybrid chaotic mapping algorithm (HCM) based on 1‐DCM (one‐dimensional chaotic
map) and Lorenz is proposed to address the security issues of low‐dimensional chaotic …

We study non-linear data-dimension reduction. We are motivated by the classical linear
framework of Principal Component Analysis. In nonlinear case, we introduce instead a new …

By way of concrete presentations, we construct two infinite-dimensional transforms at the
crossroads of Gaussian fields and reproducing kernel Hilbert spaces (RKHS), thus leading …
