A Generative Approach for Image Registration of Visible-Thermal (VT) Cancer Faces

no code implementations23 Aug 2023 Catherine Ordun, Alexandra Cha, Edward Raff, Sanjay Purushotham, Karen Kwok, Mason Rule, James Gulley

Since thermal imagery offers a unique modality to investigate pain, the U. S. National Institutes of Health (NIH) has collected a large and diverse set of cancer patient facial thermograms for AI-based pain research.

When Visible-to-Thermal Facial GAN Beats Conditional Diffusion

no code implementations18 Feb 2023 Catherine Ordun, Edward Raff, Sanjay Purushotham

Thermal facial imagery offers valuable insight into physiological states such as inflammation and stress by detecting emitted radiation in the infrared spectrum, which is unseen in the visible spectra.

Generating Thermal Human Faces for Physiological Assessment Using Thermal Sensor Auxiliary Labels

1 code implementation15 Jun 2021 Catherine Ordun, Edward Raff, Sanjay Purushotham

These combined data are captured from similar sensors in order to bootstrap the training and transfer learning task, especially valuable because visible-thermal face datasets are limited.

The Use of AI for Thermal Emotion Recognition: A Review of Problems and Limitations in Standard Design and Data

no code implementations22 Sep 2020 Catherine Ordun, Edward Raff, Sanjay Purushotham

But we also propose that thermal imagery may provide a semi-anonymous modality for computer vision, over RGB, which has been plagued by misuse in facial recognition.
