An alternative approach to mapping pigments in paintings with hyperspectral reflectance image cubes using artificial intelligence

open access: yesHeritage Science, 2020
Spectral imaging modalities, including reflectance and X-ray fluorescence, play an important role in conservation science. In reflectance hyperspectral imaging, the data are classified into areas having similar spectra and turned into labeled pigment ...

A Gene Locus Responsible for Reticulate Pigmented Anomaly of the Flexures Maps to Chromosome 17p13.3 [PDF]

open access: yesJournal of Investigative Dermatology, 2006
Reticulate pigmented anomaly of the flexures (RPAF), also called Dowling-Degos disease, is a rare autosomal-dominant cutaneous disorder characterized by spotted and reticulate pigmentation of the flexures. The gene, or even the chromosomal location, for RPAF has not yet been identified.

An AI‐Enabled All‐In‐One Visual, Proximity, and Tactile Perception Multimodal Sensor

open access: yesAdvanced Robotics Research, EarlyView.
Targeting integrated multimodal perception of robots, an AI‐enabled all‐in‐one multimodal sensor is proposed. This sensor is capable of perceiving three types of modalities, including vision, proximity, and tactility. By toggling an ultraviolet light and adjusting the camera focus, it switches smoothly between multiple perceptual modalities, enabling ...

In Vivo Microplastic Detection With Photoacoustic Imaging

open access: yesAdvanced Science, EarlyView.
ABSTRACT Microplastics are posing an escalating threat to both ecological systems and human health. Yet, current methods for investigating their bioaccumulation are highly invasive, requiring destructive analysis of ex vivo tissues via mass spectrometry, dye labelling, or Raman microspectroscopy.

Solid Harmonic Wavelet Bispectrum for Image Analysis

open access: yesAdvanced Science, EarlyView.
The Solid Harmonic Wavelet Bispectrum (SHWB), a rotation‐ and translation‐invariant descriptor that captures higher‐order (phase) correlations in signals, is introduced. Combining wavelet scattering, bispectral analysis, and group theory, SHWB achieves interpretable, data‐efficient representations and demonstrates competitive performance across texture,
