360-Degree VR Video Watermarking Based on Spherical Wavelet Transform
(2021)Similar to conventional video, the increasingly popular 360 virtual reality (VR) video requires copyright protection mechanisms. The classic approach for copyright protection is the introduction of a digital watermark into ... -
Applications of Informatics in a Leonardo da Vinci project with reference to the organic farming in Greece and Europe
(2011)The market of organic products in Europe is generally expanding. The organic food production has been strictly regulated in the European Union. Particular competence requirements need to be developed not only to achieve ... -
An efficient implementation on a low cost FPGA for photon detection in nuclear imaging
(2010)The aim of this study is to propose and evaluate a simple, open source, data acquisition (DAQ) tool, which provides accurate results for nuclear imaging applications. For this purpose a Xilinx Spartan3E Starter Kit, which ... -
High pressure processing at ultra-low temperatures: Inactivation of foodborne bacterial pathogens and quality changes in frozen fish fillets
(2021)High pressure processing (HPP) at ultra-low temperatures was conducted against Listeria monocytogenes and Salmonella enterica in frozen pink salmon fillets. Quality changes, such as drip loss, color and odor attributes ... -
Improved hybrid blind IQA using alternative NSS characterization in the spatial domain
(2021)The adoption of a Natural Scene Statistics (NSS) model has been an important research direction in the selection of perceptual features capable of giving satisfactory results in the problem of image quality assessment ... -
PET Counting Response Variability Depending on Tumor Location, Activity, and Patient Obesity: A Feasibility Study of Solitary Pulmonary Nodule Using Monte Carlo
(2019)We aim to investigate the counting response variations of positron emission tomography (PET) scanners with different detector configurations in the presence of solitary pulmonary nodule (SPN). Using experimentally validated ... -
Power reduction in an H.264 encoder through algorithmic and logic transformations
(2006)The H.264 video coding standard can achieve considerably higher coding efficiency than previous video coding standards. The keys to this high coding efficiency are the two prediction modes (Intra & Inter) provided by H.264. ...
