Assessing Analytical Methods for the Rapid Detection of Lead Adulteration in the Global Spice Market
Lead adulteration of spices, primarily via Pb chromate compounds, has been documented globally as a growing public health concern. Currently, Pb detection in spices relies primarily on expensive and time-consuming laboratory analyses. Advancing rapid Pb de ...
AMER CHEMICAL SOC2022The High-Quality Wide Multi-Channel Attack (HQ-WMCA) database
Sébastien Marcel, Guillaume Heusch, Zohreh Mostaani
The High-Quality Wide Multi-Channel Attack database (HQ-WMCA) database extends the previous Wide Multi-Channel Attack database(WMCA) \citegeorge_mccnn_tifs2019, with more channels including color, depth, thermal, infrared (spectra), and short-wave infrared ...
Idiap2020Aliasing mitigation in optical microscopy of dynamic biological samples by use of temporally modulated color illumination and a standard RGB camera
Michael Stefan Daniel Liebling, Christian Jaques
Significance: Despite recent developments in microscopy, temporal aliasing can arise when imaging dynamic samples. Modern sampling frameworks, such as generalized sampling, mitigate aliasing but require measurement of temporally overlapping and potentially ...
SPIE-SOC PHOTO-OPTICAL INSTRUMENTATION ENGINEERS2020CED: Color Event Camera Dataset
Event cameras are novel, bio-inspired visual sensors, whose pixels output asynchronous and independent times-tamped spikes at local intensity changes, called ‘events’. Event cameras offer advantages over conventional frame-based cameras in terms of latency ...
IEEE2019Point cloud quality evaluation: Towards a definition for test conditions
Touradj Ebrahimi, Evangelos Alexiou, Rafael Xavier Meriade Duarte
Recently stakeholders in the area of multimedia representation and transmission have been looking at plenoptic technologies to improve immersive experience. Among these technologies, point clouds denote a volumetric information representation format with i ...
2019Simultaneous Geometric and Radiometric Calibration of a Projector-Camera Pair
Sabine Süsstrunk, Marjan Shahpaski
We present a novel method that allows for simultaneous geometric and radiometric calibration of a projector-camera pair. It is simple and does not require specialized hardware. We prewarp and align a specially designed projection pattern onto a printed pat ...
IEEE2017Color changing effects with cross-halftone prints on metal
We propose new methods for creating color varying prints with classical cyan, magenta, yellow inks on a metallic substrate. We use a special crossline halftone with optimized surface coverages of the inks to create color prints on a metallic surface whose ...
2017THz streak camera method for synchronous arrival time measurement of two-color hard X-ray FEL pulses
Leonid Rivkin, Rasmus Ischebeck, Christoph Peter Hauri, Ishkhan Gorgisyan
The two-color operation of free electron laser (FEL) facilities allows the delivery of two FEL pulses with different energies, which opens new possibilities for user experiments. Measuring the arrival time of both FEL pulses relative to the external experi ...
Optical Society of America2017Method to produce a full-color smoothed image
The present invention aims at providing a method to produce modified images of a human face while removing all defects, such as such as pigmentation irregularities (e.g., moles, freckles), irritation, roughness, or wrinkles This is achieved thanks to a met ...
2016JPEG XT: A Compression Standard for HDR and WCG Images [Standards in a Nutshell]
Touradj Ebrahimi, Philippe Hanhart
High bit depth data acquisition and manipulation have been largely studied at the academic level over the last 15 years and are rapidly attracting interest at the industrial level. An example of the increasing interest for high-dynamic range (HDR) imaging ...
