From Model to Practice: Testing Near‐Infrared Spectroscopy as a Bone Collagen Prescreening Tool
Archaeometry, EarlyView.ABSTRACT Collagen is a vital archaeological material, preserving biochemical signatures that provide insights into past environments, diets, and human–animal interactions. However, diagenetic processes can lead to rapid and often inconspicuous degradation of collagen. Given the variability in collagen preservation and its significance for analyses such

Enhanced LSB image steganography method using knight tour algorithm, vigenere encryption and LZW compression [PDF]
, 2013 The challenge of steganographic methods is to create a rational balance between the quality of the file and the size of data that can be transferred. In addition, the robustness of the technique and security of the obscure data are the facts that cannot ...

A LSB substitution compatible steganography
, 2009 [[abstract]]©2007 IEEE-Substituting the least-significant-bits (LSBs) of an image is the easiest and most popular scheme in information hiding. Works have been done to point out this algorithm can be detected by some steganalysis techniques. One of these

Computer Graphics Forum, EarlyView.Abstract Typography is an essential component of visual communication. Editing and animating text appearance for graphic designs, title sequences, commercials, and logos remain highly skilled tasks requiring detailed, hands‐on efforts from pro artists. Automating these challenging manual workflows requires balancing the competing goals of maintaining a

Data Hiding in Images by Hybrid LSB Substitution
, 2010 [[abstract]]In this paper, two hybrid LSB substitution image hiding methods are proposed. The first method couples two previous works, the optimal LSB substitution and the optimal pixel adjustment process (OPAP), to improve the quality of the stego-image.

Does Visual Working Memory Decline Explain Age Differences in Visualization Performance?
Computer Graphics Forum, EarlyView.Abstract Visualization studies that examine age effects on task performance often attribute the performance gap between young adults (YA) and people in late adulthood (PLA) to declines in cognitive abilities, especially reduced visual working memory (VWM) capacity.

Computer Graphics Forum, EarlyView.Abstract Visualization is routinely used in control rooms to maintain situational awareness of complex sociotechnical systems. While control room design often incorporates human factors engineering to identify the information presented, it is not unusual for control room visual encodings to rely closely on operator experience and historical encodings ...

LSB-based High-Capacity Data Embedding Scheme for Digital Images
, 2009 [[abstract]]In this paper, an improved LSB replacement scheme having a high payload is proposed. In this scheme, a secret stream is transformed into a secret sequence by using a 3n-base notational system and the secret sequence is embedded into a pixel ...
