Software like this would be especially helpful to missing children searches, Seattle TV station KOMO News reports. Right now, expert artists try to help with searches by making drawings of missing kids at their current age. The artists use a combination of photos of the kids, the looks of the kids' older family members, and current knowledge about how faces age. (Scientists already know, for example, that people's faces and noses lengthen as they get older.) The craft of interpolating how a person will have aged is "part art, part science and a little intuition," as one firm describes it.
