Researcher chirpy about birdapp prospects

- JOHN GIBB

UNIVERSITY of Otago doctoral candidate Tapabrata Chakrabort­i is excited that his research is paving the way for a smartphone app enabling tourists to identify ‘‘our national treasure’’ of birds.

Indianborn Mr Chakrabort­i recently completed his computer science doctorate and his research findings had been ‘‘well received in leading peerreview­ed internatio­nal conference­s’’, he said.

New Zealand was home to many endemic or native birds, and many of them were also threatened or endangered.

These birds were of interest not only to experts, but also to birdwatche­rs and the general public.

Tablets and mobile phones now made it potentiall­y possible for anyone to become a birdwatche­r.

But this had required research into adopting artificial intelligen­ce and machine learning techniques and developing robust apps.

The Otago computer science department had recently been conducting research in this field, mainly through Mr Chakrabort­i’s doctoral work and his supervisor­s, Drs Brendan McCane and Steven Mills.

The main challenge was to ‘‘make the algorithm learn the subtle difference­s between similarloo­king birds’’ such as kea and kaka.

The project’s ‘‘future and final goal’’ would be to translate these algorithms into a userfriend­ly app that could operate as a digital birdwatche­r.

A user would photograph a bird on a mobile device and the app would suggest the bird’s name.

New Zealand research could also be integrated into an existing bird app, such as one operated by Cornell University, in the United States, which mainly focused on North American and European birds.

Mr Chakrabort­i would also, from March, undertake postdoctor­al study at Oxford University, England, on the use of artificial intelligen­ce in medical imaging.

He hoped other researcher­s would further develop his birdrecogn­ition work.
