Significance: Measurement and imaging of hemoglobin oxygenation are used extensively in
the detection and diagnosis of disease; however, the applied instruments vary widely in their …

Simple Summary Kaposi's sarcoma, a rare opportunistic tumor, is observed in four
epidemiological conditions (AIDS-related, iatrogenic, endemic or classic KS). Although in …

In vivo quantitative assessment of skin lesions is an important step in the evaluation of skin
condition. An objective measurement device can help as a valuable tool for skin analysis …

This study introduces an integrated training method combining the optical approach with
ground truth for skin pigment analysis. Deep learning is increasingly applied to skin pigment …

Hyperspectral imaging (HSI) provides more detailed information than red-green-blue (RGB)
imaging, and therefore has potential applications in computer-aided pathological diagnosis …

Hyperspectral imaging (HSI) can estimate the spatial distribution of skin blood oxygenation,
using visible to near-infrared light. HSI oximeters often use a liquid-crystal tunable filter, an …

Extraction of spectral information using liquid crystal (LC) retarders has recently become a
topic of great interest because of its importance for creating hyper-and multispectral images …

Diffusion geometry techniques are useful to classify patterns and visualize high-dimensional
datasets. Building upon ideas from diffusion geometry, we outline our mathematical …

We report a second derivative multispectral algorithm for quantitative assessment of
cutaneous tissue oxygen saturation (StO 2). The algorithm is based on a forward model of …

Skin flaps are complex procedures used extensively in reconstructive surgery that require
post-operative monitoring to ensure that they do not fail. Near infrared (NIR) spectroscopic …
