Biologists at the University of Vienna have developed a goose facial recognition tool using AI, achieving an accuracy rate of 97%. The tool collects facial images of geese and focuses on beak features to accomplish facial recognition. Research shows that geese can recognize photos of their companions and friends, and facial recognition is key to their social interactions. Similar tools have been developed to identify individual harbor seals, providing a stress-free and simple method for animals. Facial recognition technology will be applied in areas such as biodiversity conservation, enhancing research efficiency.
