Any pet owner who has spent days hanging posters, making phone calls and knocking on neighbors' doors hopes there's a better way to find a lost dog.
That became a reality when facial recognition technology reunited a pet at San Diego County Animal Services. Joanne Cox's family in San Diego turned to FindingRover.com, a website and app. It uses technology built by university researchers, to reconnect with their dog Roxy, a Shiba inu.
The website keeps a database of photos from the three county shelters. It tries to match eight distinctive facial markers on dogs. Eyes and noses are important areas, including eye size and their position near the snout.
FindingRover.com founder John Polimeno wants to expand the photo database to improve the odds of more happy endings.
The website is unique in using facial recognition but stands among many online tools people increasingly use to find lost pets. There are alarm systems, social media alerts and apps that post rewards or call people in neighborhoods.
Plus, the American Society for the Prevention of Cruelty to Animals has its own mobile app for recovering missing pets. It offers tips on the best ways to search and allows users to create a digital flier to share on social media.
Facial recognition worked for the Cox family after Roxy bolted during a thunderstorm in late July. Five days after the dog disappeared, the family's 10-year-old daughter created a free Finding Rover account. The technology matched her uploaded photo to one taken at the shelter.
"Within four hours of her arrival to the shelter, we were there to pick her up," Joanna Cox said in an email.
Every dog entering San Diego County's three shelters is added to the photo database. Daniel deSousa, the system's deputy director, says the program can work two ways:
Someone finds a dog, takes its picture and sends it to the database, where a match generates a notice to the owner. The owner then can call the good Samaritan and arrange a pickup.
Dogs coming in to the shelters have their photos run against the database. If there's a match, the owner gets a call.
Critical thinking challenge: John Polimenos system depends upon two different photos taken by two different people. Why?
