Analysis of watermarking techniques with wavelet and cosine transform for imperceptibility on image

, 2021
Some medical image watermarking techniques utilize frequency transform domains to improve the performance of the watermarking technique, where the main requirement of the medical image is to maintain the visual quality.

Dissecting the Imperceptible [PDF]

Critique d’art, 2011
Encouraged by his museum experience as curator at the Mamco in Geneva, Thierry Davila offers us the recent history of the flipside of art, the one played out on the borderlines of the perceptible, where extreme tenuousness is presented as the actual motif of creation. His book, which is an offshoot of his doctoral thesis, supervised by Eric Michaud and

Image Vividness Changes due to White‐Boosting on WOLED Display

Journal of the Society for Information Display, EarlyView.
White‐Boosting is a display technique for RGBW WOLED panels that increases peak brightness. This study investigated its effect on perceived image vividness using paired‐comparison experiments. Across three psychophysical experiments, higher White‐Boosting consistently enhanced perceived vividness.

A Hybrid Region-Based Approach for Image Steganography

Zanco Journal of Pure and Applied Sciences
Steganography is the process of embedding a hidden message in a cover that is undetectable to unknown receivers. Since digital images have a high degree of redundancy that can be utilized for concealing a message, image steganography has been one of the ...

Hughlings Jackson's "imperception" and anosognosia [PDF]

Journal of Neurology, Neurosurgery & Psychiatry, 2002
One of the earliest to attempts to localise specific functions to anatomical regions of the brain was that of Franz Joseph Gall,1 who distinguished six varieties of memory, which he localised in the frontal lobes. Auburtin in 1864 related the faculty of language to the frontal lobes, and Broca2 and Dax highlighted the left side of the brain.3 The right

MRI‐based deep learning models match or surpass physician performance for early detection and staging of avascular necrosis of the femoral head: A systematic review

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose Efficient and reliable magnetic resonance imaging (MRI)‐based diagnosis of early avascular necrosis of the femoral head (AVNFH) is essential for guiding treatment but remains challenging due to variability in clinician experience. Deep learning (DL) models offer a promising solution. This review evaluates and summarizes the performance

Feature Image Watermarking Based on Bicubic Interpolation of Wavelet Coefficients Using CRT

CommIT Journal, 2017
The main objective of watermarking method is to improve the robustness and imperceptibility. This paper introduces an improved CRT watermarking method using absolute value of interpolated wavelet coefficients aiming to improve the imperceptibility and ...

Imperception

Terrain
Depuis 2012, un différend épisté- mologique oppose Aparecida Vilaça et Tanya Luhrmann au sujet du statut à accorder à l’invisible. Dans cet article, nous défendons l’idée selon laquelle ce genre de débat est mieux rendu si on l’aborde à partir de la catégorie d’« imperception » : on désigne par là le rapport que nous entretenons à ce qu ...

Reachable Workspace as a Clinical Outcome for Upper Extremity Function: A Narrative Review

Muscle &Nerve, EarlyView.
ABSTRACT Motion sensing technology can be utilized to capture detailed upper extremity (UE) motion to reconstruct an individual's three‐dimensional (3D) reachable workspace (RWS). The RWS can be quantified as relative surface area (RSA), providing an innovative surrogate measure to assess UE mobility and function.
