Abstract: Automated acoustic recognition of species aims to provide a cost-effective method for biodiversity monitoring. This is particularly appealing for detecting endangered animals with a distinctive call, such as the New Forest cicada. To this end, we pursue a crowdsourcing approach, whereby the millions of visitors to the New Forest will help to monitor the presence of this cicada by means of a smartphone app that can detect its mating call. However, current systems for acoustic insect classification are aimed at batch processing and not suited to a real-time approach as required by this system, because they are too computationally expensive and not robust to environmental noise. To address this short-coming we propose a novel insect detection algorithm based on a hidden Markov model to which we feed as a single feature vector the ratio of two key frequencies extracted through the Goertzel algorithm. Our results show that this novel approach, compared to the state of the art for batch insect classification, is much more robust to noise while also reducing the computational cost.

Davide's Hunt for Cicadas in Slovenia20th June 2012
The New Forest Cicada is an insect native to the UK in great danger of becoming extinct. Several entomologists have searched for it in the past few years, but no sighting has been confirmed for over a decade. However, the area where the cicada could be found is vast, extending to the entire New Forest. This cicada makes a high-pitched call that is difficult for humans to hear.
Davide's research is investigating whether pervasive sensing technology can leverage the smartphones of visitors to t... [more]
Crutch Research in Government Report10th December 2010
Our research on instrumented crutches for rehabilitation has been featured in an annual government report on assistive technology. Our bit can be found on page 29 of the report (follow the link at the bottom of this news item).
The report is prepared by FAST (the Foundation of Assistive Technology), and is an annual publication by the Department of Health (UK Government). The report has a number of uses (including giving researchers an overview of other work in the field, and service provider... [more]
