Remote photoplethysmography (rPPG) enables non-contact monitoring of biomedical signals using a camera, making it suitable for telemedicine and remote health monitoring. This paper proposes an end-to-end convolutional neural network (CNN) model for estimating blood oxygen saturation (SpO2) from video data. The model is trained and evaluated on a publicly available dataset, showing promising results in accurately estimating SpO2 levels. The proposed approach has the potential to enhance remote health monitoring systems by providing a non-invasive method for SpO2 estimation.
