“There is some previous work that tries to create a 3D character using multiple viewpoints,” said Brian Curless, a professor at University of Washington. From there, it matches a 3D template to the subject’s body position. Photo Wake-Up stores 3D information for each pixel: its distance from the camera or artist and how a person’s joints are connected together. It also generates the back of the person by using information from the image and the 3D template. Then the tool stitches the two sides together to make a 3D person who will be able to turn around.
