rPPG Extraction and Heart Rate Detection

Posted 4 weeks ago

Overview of the Project
We are seeking your expertise in developing a robust pipeline for the collection of remote
photoplethysmography (rPPG) signals and subsequent heart rate calculation.
The primary objective of this project is to collect highly accurate rPPG signals while
minimizing mean square error. The input sensor for signal collection will primarily be a
camera, with various specifications ranging from 2MP to 6MP or even a web streaming link
providing live streams. The parameters of these streams, including FPS (frames per second),
bitrate, height, width, and codecs, may vary significantly. Hence, it is imperative to build a
robust pipeline capable of controlling and standardizing these variables to ensure consistent
rPPG signal generation.

Key Tasks
1. Develop a Pipeline Control System: Design and implement a pipeline control system
capable of managing FPS variation, bitrate fluctuation, and stream dimension
variations. This system should be flexible enough to accommodate different camera
specifications and streaming sources.

2. Standardize Video Collection Pipeline: Create a standardized video collection pipeline
to ensure consistent rPPG signal generation across different camera types and
streaming sources. This pipeline should include procedures to account for variations
in lighting conditions, camera angles, and skin tone(PSNR).

3. Signal Processing for rPPG Extraction: (Supervised or unsupervised your perspective)
Develop algorithms for extracting rPPG signals from the collected videos. These
algorithms should prioritize accuracy and reliability while minimizing noise and
artifacts. A signal with low MSE high SNR values as well as Pearson correlation
coefficient beyond 0.90.

4. Heart Rate Calculation: Utilize the extracted rPPG signals to calculate heart rates
accurately. Ensure that the heart rate calculation algorithm accounts for variations in
signal quality and noise levels.

Expected Deliverables
1. Detailed design specifications for the pipeline control system and video collection
pipeline.

2. Implemented pipeline control system capable of managing FPS, bitrate, and stream
dimensions.

3. Standardized video/stream collection pipeline.

4. Signal processing algorithms for rPPG extraction.

5. Heart rate calculation algorithm integrated with the rPPG extraction module.

6. Comprehensive documentation outlining the implementation details, testing
procedures, and performance evaluation metrics.
