AIR-400 (incl. AIR-125)

annotated infant respiration videos from overnight baby monitors (18 infants, 400 clips, Northeastern, WACV 2026)

AIR-400 is a Northeastern University (Augmented Cognition Lab) dataset for video-based infant respiration estimation. It combines the earlier AIR-125 set (125 clips from 8 infants, 2023) with 275 new clips from 10 more infants from the same study, giving 400 short videos from 18 infants aged about 4 to 11 months. Clips were cut from overnight baby-monitor footage (RGB and infrared) recorded at home under Northeastern IRB approval, and each has a respiration waveform built from manual frame-by-frame breath annotations.

Original description

The development of contactless respiration monitoring for infants could enable advances in the early detection and treatment of breathing irregularities, which are associated with neurodevelopmental impairments and conditions like sudden infant death syndrome (SIDS). But while respiration estimation for adults is supported by a robust ecosystem of computer vision algorithms and video datasets, only one small public video dataset with annotated respiration data for infant subjects exists, and there are no reproducible algorithms which are effective for infants. We introduce the annotated infant respiration dataset of 400 videos (AIR-400), contributing 275 new, carefully annotated videos from 10 recruited subjects to the public corpus. We develop the first reproducible pipelines for infant respiration estimation, based on infant-specific region-of-interest detection and spatiotemporal neural processing enhanced by optical flow inputs. We establish, through comprehensive experiments, the first reproducible benchmarks for the state-of-the-art in vision-based infant respiration estimation. We make our dataset, code repository, and trained models available for public use.
