Abstract
An effective and unobtrusive procedure for
measuring heart rate can be extremely useful as
an aid in rapid assessment of physical and mental
condition. The primary aim of this paper is to
present a computer system, developed by the
authors, for remote heart rate measurement using
a commercial camera.
Except for a quick assessment of the physical
condition, the computer system can be used in
conjunction with affective multimedia databases
for different forms of psychotherapy such as
biofeedback or cognitive-behavioral therapy. The
system utilizes the OpenCV open-source library
to estimate the heart rate by processing subject’s
facial images. All data is stored in the relational
database for later analysis. The client segment of
the system is completely mobile. System accuracy
was evaluated in an experiment. The results
indicate that this technology can be successfully
used to measure heart rate in a rest state, while
further optimization is required for measurement
during or after physical activities.
