A teenager from New York has invented a low-cost tool to spot elephant poachers(偷猎者) in real time.
Anika Puri, 17, won the 2022 Peggy Scripps Award for Science Communication for her model of a machine-learning-driven software that 41 movement patterns in thermal infrared(热红外线) videos of humans and elephants.
"I'm very excited by the 42 focusing on endangered species and environmental science," Puri said.
During a recent trip to India, Puri realized that elephants were still being 43 for their tusks."I was quite shocked." Puri said. "Because I always thought. ‘Well, poaching is 44 : how come it really is still such a big 45 ?"
Over the next two years, Puri 46 the software EISa (short for elephant savior). This wildlife poacher detection solution is based on a 47 process: an EISa camera attached to an iPhone 48 over a park on a drone(无人机) and 49 the movements of elephants or humans.
Puri says the software is four times more 50 than existing state-of-the-art detection methods. It also removes the 51 for expensive high-resolution(高分辨率的) thermal cameras.
The 17-year-old's invention has earned 52 from notable scientists. "Puri's software is quts admirable", says Jasper Eikelboom, an ecologist. "It's quite 53 that a senior high school student has been able to 54 such a solution like this. Not only the research and the analysis but also being able to 55 it in the models."
