Thermosensation

Thermosensation

Peripheral thermosensation is the perception of external temperature. A change in temperature (on the surface of the skin and other tissues) is detected by a family of temperature-sensitive ion channels called Transient Receptor Potential, or TRP, receptors. These receptors are located on free nerve endings. Those detecting cold temperatures are closer to the surface of the skin than the nerve endings detecting warmth. These thermoTRP channels, while temperature selective, have relatively...

Assessing Body Temperature - Temporal Artery

Assessing Body Temperature - Temporal Artery

Here is a stepwise guide to assessing the body temperature at the temporal artery using a temporal artery thermometer
Step 1: Perform hand hygiene and don a fresh pair of gloves to prevent cross-infection and ensure patient safety.
Step 2: Explain the procedure to the patient to establish trust. Clear communication establishes trust with the patient, ensures they understand what to expect, promotes cooperation, and enhances comfort during the procedure.
Step 3: Assess the patient's...

Thermal Strain

Thermal Strain

Thermal strain is a concept that arises when we consider how temperature changes affect structures. Unlike the conventional assumption that structures remain constant under load, real-world scenarios often involve temperature fluctuations that can significantly impact these structures. Consider a homogeneous rod with a uniform cross-section resting freely on a flat horizontal surface. If the rod's temperature increases, the rod elongates. This elongation is proportional to the temperature...

Area of Science:

Materials Science
Computer Vision
Art Conservation Science

Background:

Infrared thermography is a key nondestructive testing method for artwork.
Raw thermograms often have noise and limited data, hindering accurate defect detection.
Advanced data enhancement techniques are needed to improve thermographic analysis.

Purpose of the Study:

To develop and evaluate deep learning methods for enhancing thermographic data for artwork inspection.
To improve defect detectability in artwork using enhanced thermograms and principal component analysis.

Main Methods:

Proposed a defect inspection method combining Principal Component Analysis (PCT) with deep learning.
Utilized Spectral Normalized Generative Adversarial Network (SNGAN) for data augmentation.
Employed Convolutional Autoencoder (CAE) for thermographic image quality enhancement.

Main Results:

SNGAN integration improved signal-to-noise ratio by 1.08%.
CAE integration enhanced signal-to-noise ratio by 8.73%.
Both deep learning methods, when combined with PCT, improved defect detectability compared to PCT alone.

Conclusions:

Deep learning-based thermographic data enhancement significantly improves defect detection in artwork.
CAE shows superior performance in enhancing image quality and defect visibility.
The proposed integrated approach offers a promising solution for nondestructive artwork inspection.
