A Novel Robust Reversible Watermarking Scheme for Protecting Authenticity and Integrity of Medical Images

IEEE Access, 2019
It is of great importance in telemedicine to protect authenticity and integrity of medical images. They are mainly addressed by two technologies, which are region of interest (ROI) lossless watermarking and reversible watermarking.

In‐vitro puncture experiment using alligator teeth tracks the formation of dental microwear and its association with hardness of the diet

The Anatomical Record, EarlyView.
Abstract With the development of dental microwear texture analysis (DMTA), there has been an increasing application of DMTA for dietary estimation in extant and fossil reptiles, including dinosaurs. While numerous feeding experiments exist for herbivorous mammals, knowledge remains limited for carnivorous reptiles. This study aimed to qualitatively and

T. rex cognition was T. rex‐like—A critical outlook on diverging views of the neurocognitive evolution in dinosaurs

The Anatomical Record, EarlyView.
Abstract A recent debate has emerged between Caspar et al. (2024) and Herculano‐Houzel (2023) on inferring extinct dinosaur cognition by estimating brain neuron counts. While thought‐provoking, the discussion largely overlooks the function of cognition, as well as partly neglects the difficulties involved in estimating neuron numbers, which according ...

A Fragile Watermarking Chaotic Authentication Scheme Based on Fuzzy C-Means for Image Tamper Detection

, 2017
In the last two decades, several fragile watermarking schemes have been proposed for image authentication. In this paper, a novel fragile watermarking authentication scheme based on Chaotic Maps and Fuzzy C-Means (FCM) clustering technique is proposed ...

Multi‐method analysis for the three‐dimensional reconstruction of muscle fascicles from DiceCT datasets

The Anatomical Record, EarlyView.
Abstract Muscle architecture is a major determinant of muscle performance and, in mammalian lineages, has been correlated with both feeding ecology and locomotor behaviors. Over the past decade, contrast‐enhanced micro‐CT (DiceCT) has emerged as an alternative to traditional dissection‐based measurement.

Patterns of interspecific variation in labial microarchitecture among anthropoid primates and the evolution of the hominin lips

The Anatomical Record, EarlyView.
Comparative histological and semi‐automated image analysis of primate lips: Masson's trichrome‐stained sagittal sections were segmented to quantify the connective tissue, adipose, and muscular components, enabling interspecific comparisons of labial architecture.

Tamper Localization Approach for Reversible Watermarking Algorithm Based on Histogram Bin Shifting [PDF]

, 2015
Reversible watermarking is a process which is used to authenticate the multimedia content. It checks the integrity of the digital data in order to recover the original data without any distortion.
