Title: Innovations by Si Wu in Camera-Based Stress Determination

Introduction

Si Wu is an accomplished inventor based in Newmarket, Canada. He has made significant contributions to the field of stress determination through innovative technologies. With a total of two patents to his name, Wu's work focuses on utilizing advanced machine learning techniques to assess stress levels in individuals.

Latest Patents

Si Wu's latest patents include a groundbreaking system and method for camera-based stress determination. This method involves determining a plurality of regions-of-interest (ROIs) of a body part. It also includes analyzing a captured image sequence for each ROI to represent hemoglobin concentration (HC) changes using a trained machine learning model. The model is trained with a hemoglobin concentration changes training set, which utilizes bitplanes from previously captured image sequences of other individuals as input. The method further determines an HC change signal for each ROI based on changes in the set of determined bitplanes. Additionally, it calculates intervals between heartbeats, determines heart rate variability, and ultimately assesses a stress level based on the standard deviation of the heart rate variability.
