The Echoes of Flowers

To detect plants, bats emit ultrasonic pulses and decipher the various echoes that return. A research group in Tübingen, Germany has developed a computer model to imitate this process of plant identification.

Computers Show How Bats Classify Plants According To Their Echoes

ScienceDaily (Mar. 24, 2008) — Researchers have developed a computer algorithm that can imitate the bat's ability to classify plants using echolocation. The study represents a collaboration between machine learning scientists and biologists studying bat orientation.

As bats can hear their way to favorite plants, so can a computer program produce distinct patterns of different plant species (top panels) purely from sonar reflections.
