There ’s anew persona algorithm called SparkleVisionin township , and yes , it involves glitter . A glitter - coat surface , you see , is really just a carpenter’s plane of many , many tiny mirrors . And a shattered glitter - reflection can indeed be reconstructed into the face of Obama .
Before there was SparkleVision , there was a glitter board . A trio of MIT scientist started by meditate images on a information processing system covert off the board and photographing the reflexion . To the human center , the glitter reflection is just a shimmery surface . But each patch of glister is also a small , randomly oriented mirror , what the scientists wonderfully call a “ random specular microfacet ” in theirpaper upload to ArXiv .
By comparing several images before and after reflection , they were able to create an algorithm that map each pel of the original effigy to its reflection in sparkle . So here you have it , Marilyn Monroe and Albert Einstein emerging out of shimmery frill .
But there ’s more to SparkleVision then shits and giggles . While this initial iteration of SparkleVision is bound to the exact set - up used in the paper , the researchers trust to finally apply it to forensic Reconstruction Period of reflexion from other similarly lustrous physical object — such as sealed metals , fabric , and wet surface .
