Query: Home Activity Monitoring using Low Resolution Infrared Sensor   Action monitoring in a home environment provides important information for
health monitoring and may serve as input into a smart home environment. Visual
analysis using cameras can recognise actions in a complex scene, such as
someones living room. However, although there the huge potential benefits and
importance, specifically for health, cameras are not widely accepted because of
privacy concerns. This paper recognises human activities using a sensor that
retains privacy. The sensor is not only different by being thermal, but it is
also of low resolution: 8x8 pixels. The combination of the thermal imaging, and
the low spatial resolution ensures the privacy of individuals. We present an
approach to recognise daily activities using this sensor based on a discrete
cosine transform. We evaluate the proposed method on a state-of-the-art dataset
and experimentally confirm that our approach outperforms the baseline method.
We also introduce a new dataset, and evaluate the method on it. Here we show
that the sensor is considered better at detecting the occurrence of falls and
Activities of Daily Living. Our method achieves an overall accuracy of 87.50%
across 7 activities with a fall detection sensitivity of 100% and specificity
of 99.21%.
