Abstract

To achieve accurate and stable contactless heart rate estimation under lighting changes and head motion conditions, this paper proposed an end-to-end heart rate estimation model called rPPG-UNet, which was based on the U-Net model and incorporated a multi-head self-attention mechanism. The model realized the extraction and reconstruction of physiological features by using the U-shaped encoder-decoder network structure, and used Skip Connection to connect the encoder and decoder to realize the multiplexing of shallow temporal features. The model also incorporated a multi-head self-attention mechanism to capture the temporal dependencies of physiological features. Finally, the model adopted a multi-task learning strategy to improve the accuracy of heart rate estimation and accelerate network training. Experimental results on public datasets show that rPPG-UNet outperforms other baseline models and can achieve more accurate contactless heart rate estimation.
