TFW: Annotated Thermal Faces in the Wild Dataset

This dataset contains thermal images of faces acquired in various environments: controlled indoor (c-indoor), semi-controlled indoor (s-indoor), and uncontrolled outdoor (u-outdoor). The c-indoor subset utilizes images from the SpeakingFaces dataset. The s-indoor and u-outdoor subsets were captured using a FLIR T540 thermal camera (464x348 pixels, 7.5–14 μm wave-band, 24° field of view, iron color palette).

Each image is annotated with a face bounding box and five facial landmarks (centers of the eyes, tip of the nose, and outer corners of the mouth).

Dataset Statistics:

  • Total Images: 9,982
  • Total Labeled Faces: 16,509

Data Splits:

  • c-indoor: 142 subjects, 5,112 images, 5,112 labeled faces. Visual pairs are available.
  • s-indoor: 9 subjects, 780 images, 1,748 labeled faces. Visual pairs are available.
  • u-outdoor: 15 subjects, 4,090 images, 9,649 labeled faces. Visual pairs are not available.
