OpenThermalAction - Sample Data (Balcony Environment)

This repository provides example thermal image sequences for action recognition captured in a balcony environment:

• Single-person sports activities (Session 1): One subject performing various sports actions
• Multi-person daily interactions (Session 2): One pair of subjects performing interactive activities

Each folder contains sequential thermal images representing one action clip.

Note: Action clips with suffixes like 1_1 and 1_2 represent different camera views of the same video.

Annotation Format

Each line in annotations_train.txt or annotations_val.txt contains:

path_to_sequence label

Example:

session_1/sub_1/thermal/1_1 0
session_1/sub_1/thermal/2_1 1
session_2/exp_1/thermal/1 15

Label Mapping

• Session 1: Label = action_number - 1 (classes 0-14)
• Session 2: Label = action_number + 14 (classes 15-27)
