Digital down converter (DDC) is one of the crucial components in digital radio receiver. The
working function of DDC is to convert the frequency translation from Intermediate Frequency …

Recently, a novel scheme called grayscale-invariance reversible data hiding (RDH) has
been developed, in which the generated color marked image will have the same grayscale …

Digital watermarking has the properties such as invisibility and anti-aggression, so the
digital watermarking technology has been widely used in copyright protection, information …

This paper analyses and rectifies the shortcomings of reversible contrast mapping (RCM)
algorithm for invisible watermarking. The proposed corrected RCM algorithm is tested by …

In this paper, a hardware implementation of a data hiding technique is proposed for efficient
quality access control of images using lifting-based discrete wavelet transformation (DWT) …

This paper introduces an efficient, lightweight, invisible, blind, real-time video watermarking
system. Symmetric chaotic key encryption enhances the system's security, ensuring …

Abstract This paper presents Xilinx System Generator (XSG) model design for realization of
reversible watermarking algorithm using Difference Expansion (DE) approach in System-On …

In the digitally dominated world, to enhance the data security of digital images, this paper
proposes a hybrid algorithm. The algorithm enhances quality metrics and simultaneously …

This paper presents an improved reversible contrast mapping (RCM) algorithm for reversible
invisible watermarking (RIW) in both software and hardware platforms. Based on well-known …

Approximate computing and reversible logic have become vital concepts in designing low-
power, area-efficient datapath units for portable image and signal processing applications …
