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.

EH Network Dissemination Event15th December 2010
Today we announced the Energy Harvesting Network's first dissemination event, which will be held at the IET, London on 7th February 2011. This one-day event will provide a platform for disseminating advances in energy-harvesting technology and research in the UK.
Keynote presentations will be given by Daniel Inman and Rob van Schaijk, and these are supplemented by a full series of presentations by well-respected speakers from academia and industry. There will also be demonstrations from compa... [more]
Launch of My New Website1st January 2011
Today sees the launch of a major website redesign. Visually, it might not look like much of a change, but a lot has changed under the bonnet. Hopefully there's now a lot more information on here and, more importantly for me, it is much easier for me to actually keep it up-to-date... The three most noticeable additions that you may have spotted are:
'News and Impact': a page that contains information on major developments in my research, and specifically some of the ways that this research has... [more]
