According to foreign media reports, it is important to track the whereabouts of endangered black rhinos, but doing so in the wilderness of Namibia can be quite challenging – especially if you don’t want to label them. This requires the design of a new footprint recognition system. The software based device, called footprint recognition technology (FIT), was designed by scientists at Duke University in North Carolina. < / P > < p > the user starts with the known footprints of black rhinoceros. Then fit uses a custom algorithm to analyze the image and measure the footprint more than 100 times. The specific combination of measurements obtained is unique to the black rhinoceros. < / P > < p > when footprint photos from different regions are subsequently entered into fit, it checks whether their measured features match the data in the database. In this way, users can know where a given rhino has been since it was last observed – and they will also know that it is actually out there, rather than being killed by poachers. < / P > < p > in addition, the system can distinguish a large number of footprints taken in one place. This allows fit to roughly determine how many rhinos are in the area and allow resources such as patrol vehicles to be allocated accordingly. < / P > < p > scientists are training wildlife conservationists, land managers, local guides and anti poachers to use fit. The technology is expected to spread in Namibia, which has 90% of the world’s black rhinos. “It’s a cost-effective way to not only protect the health of rhinos and humans, but also bring an ancient tracking technology into the 21st century,” said Zoe Jewell, associate professor of the study’s co-leader Spontaneous combustion at a Guangzhou Motor vehicle intersection and other traffic lights in Shenzhen
