A Decomposition and Reconstruction Network (DRNet) focusing on the modeling of physiological features rather than noisy data, a novel cycle loss is proposed to constrain the periodicity of physiological information, and a plug-and-play Spatial Attention Block (SAB) is suggested to enhance features along with the spatial location information.
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.
Comprehensive experiments are performed to show that the proposed method not only achieves superior performance on compressed videos with high-quality videos pair, but also generalizes well on novel data with only compressed videos available, which implies the promising potential for real-world applications.
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.
Two PPG beat detectors denoted ‘MSPTD’ and ‘qppg’ performed best, with complementary performance characteristics, which can be used to inform the choice of PPGBeat detector algorithm.
This work presents a video-based and on-device optical cardiopulmonary vital sign measurement approach that leverages a novel multi-task temporal shift convolutional attention network (MTTS-CAN) and enables real-time cardiovascular and respiratory measurements on mobile platforms.
A novel learning-based method that achieves state-of-the-art performance on several heart rate estimation benchmarks extracted from photoplethysmography signals (PPG) by incorporating the statistical distribution of heart rate changes into a hidden Markov model.
Adding a benchmark result helps the community track progress.
