Endangered African elephant surveyed by satellite imagery + AI

African elephants live in the south of the Sahara Desert, and the number of African elephants is decreasing, with 20,000 individuals being killed each year by poachers for the purpose of obtaining ivory.

In order to reduce the progress of this situation, the number of African elephants is important. However, in reality, encountering poachers by chance can endanger life, making it difficult to accurately determine the number.

A team of researchers at the University of Bath in the UK, Oxford, and the University of Twente in the Netherlands created an AI that was trained by deep learning to investigate the number of African elephants living in the savannah from satellite images. This AI achieves the same precision as a human surveying the number of elephants in an aerial photograph.

An AI trained to investigate wildlife populations included counting whale populations using photographs taken over the sea. However, in the case of the sea, the accuracy of the AI could be improved relatively easily because it was enough to find the black whale shadow in a uniform blue background.

However, in the case of land, it was difficult to improve AI as it was necessary to selectively find an elephant among various colors such as vegetation and river in the soil. Satellite images are useful for researchers working for wildlife conservation because they can continuously capture vast land within a short period of time, so they can be counted from the sky and, above all, safe. In addition, the application of this technology can continuously track trends even as wild animals migrate across borders. It is said that more flexible and safer protection activities may be possible.

Not only African elephants, but also various wildlife are on the decline. AI can still count large animals like elephants, but since satellite image resolution is increasing every two to three years, the research team plans to further strengthen AI to monitor even smaller ones in the future.

Through the monthly AHC PC and HowPC magazine era, he has watched 'technology age' in online IT media such as ZDNet, electronic newspaper Internet manager, editor of Consumer Journal Ivers, TechHolic publisher, and editor of Venture Square. I am curious about this market that is still full of vitality.
