HiDURPA Dataset<\/h2>\n\n\n\n

HIDURPA (High Defi-
nition Uncompressed Remote Photoplethysmography
Acquisition<\/em>) 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.<\/p>\n\n\n\n

Recording setup<\/h2>\n\n\n\n

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.<\/p>\n\n\n\n

Ground truth measurements<\/h2>\n\n\n\n

To provide reliable reference signals for validation, the following ground truth data were recorded:<\/p>\n\n\n\n

\u2022 ECG using a Polar H10<\/p>\n\n\n\n

\u2022 BVP and SpO\u2082 waveforms using a VTM20F<\/p>\n\n\n\n

Availability & access<\/h2>\n\n\n\n

The dataset will be released upon publication of the paper:<\/p>\n\n\n\n

\u201cA STUDY OF RESOLUTION-AWARE VIDEO COMPRESSION FOR REMOTE PHOTOPLETHYSMOGRAPHY\u201d<\/p>\n\n\n\n

Access is restricted to research groups and research institutions and requires a signed Data Usage Agreement (DUA).<\/p>\n<\/div>\n<\/div>\n\n\n\n

Supplementary information<\/h2>\n\n\n\n



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 \u00b1 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 \u00b1 interquartile range) across codecs, QP levels, spatial resolutions, and datasets.<\/p>\n\n\n\n
