A STUDY OF RESOLUTION-AWARE VIDEO COMPRESSION FOR REMOTE PHOTOPLETHYSMOGRAPHY

HiDURPA Dataset

HIDURPA (High Defi-
nition Uncompressed Remote Photoplethysmography
Acquisition) is a high-definition raw video dataset designed for research in remote photoplethysmography (rPPG). The dataset includes recordings from 12 participants (4 female, 8 male), with five 30-second sessions per participant.

Recording setup

Participants were positioned approximately 1 meter in front of the camera and were instructed to stand still during acquisition. Video was captured using a Blackmagic Pocket Cinema Camera 4K and illuminated with two softboxes to ensure consistent lighting. The recordings were acquired via a Blackmagic DeckLink Mini Recorder 4K capture card in uncompressed YUV422 at 30 fps.

Ground truth measurements

To provide reliable reference signals for validation, the following ground truth data were recorded:

• ECG using a Polar H10

• BVP and SpO₂ waveforms using a VTM20F

Availability & access

The dataset will be released upon publication of the paper:

“A STUDY OF RESOLUTION-AWARE VIDEO COMPRESSION FOR REMOTE PHOTOPLETHYSMOGRAPHY”

Access is restricted to research groups and research institutions and requires a signed Data Usage Agreement (DUA).

Supplementary information

This section provides supplementary material to complement the paper, presenting the complete tabulated results and accompanying figures from our experiments on resolution- and compression-aware remote photoplethysmography (rPPG). The tables report rPPG performance (mean ± standard deviation) across different video codecs (H.264/AVC, H.265/HEVC, H.266/VVC, and AV1), quantization parameter (QP) settings, and spatial resolutions on the HiDURPA and UBFC1 datasets. The figures summarize rPPG performance (median ± interquartile range) across codecs, QP levels, spatial resolutions, and datasets.
