Projects:2016s1-105 Non-Contact Photoplethysmogram

From Projects
Jump to: navigation, search

A photolethysmogram is an optical measurement of the volume of blood in a section of the body, which can subsequently be used to extract someone's pulse rate. This is normally achieved using a contact sensor incorporating a light source and a photodetector, but can also be achieved with a non-contact camera and ambient illumination.

Project Aims

This project aims to explore the current work in non-contact photplethysmography methods. The primary deliverable of the project, for this year, will be a proof-of-concept Android app that can extract the pulse rate of a user using the front or rear camera of a smartphone. However a lot of the real value of this project will be in exploring and characterising the current research being done in this area and the development of a research framework that can be used to answer further questions in the future. There will also be a real interest in the computational complexity of any potential methods due to the interest in producing a real-time application.
