The Beam AI SDK is introduced, which can monitor user stress through the selfie camera in real-time and demonstrate an average Pearson correlation of 0.801 in determining stress and heart rate variability, thus producing commercially useful readings to derive content decisions in apps.
This paper studies the prediction of heart rate from acceleration using a wrist worn wearable and proposes an online approach to tackle the concept as time passes, which can achieve good predictive performance while using the PPG heart rate sensor infrequently.
This work uses a prototype multi-sensor wearable device to collect over 180h of photoplethysmography data sampled at 20Hz and end-to-end learning to achieve state-of-the-art results in detecting AFib from raw PPG data, bringing large-scale atrial fibrillation screenings within imminent reach.
Compared to state-of-the-art algorithms, HeartBEAT not only produces comparable Pearson's correlation and mean absolute error, but also higher Spearman's ρ and Kendall's τ.
The publicly available PW database is a valuable resource for understanding CV determinants of PWs and for the development and preclinical assessment of PW analysis algorithms.
Surprisingly, performances achieved by the four best rPPG methods, namely POS, CHROM, PCA and SSR, are not significantly different from a statistical standpoint, highlighting the importance of evaluate the different approaches with a statistical assessment.
A design space exploration methodology to automatically generate a rich family of deep Temporal Convolutional Networks (TCNs) for HR monitoring, all derived from a single “seed” model, whose most accurate model sets a new state-of-the-art in Mean Absolute Error.
The present pyVHR framework represents a multi-stage pipeline covering the whole process for extracting and analyzing HR fluctuations and supports either the development, assessment and statistical analysis of novel rPPG methods, either traditional or learning-based, or simply the sound comparison of well-established methods on multiple datasets.
Adding a benchmark result helps the community track progress.
