"When you upload an image to Fotowoosh, their software tears it apart and distinguishes the sky, ground and vertical elements within the photo, then cuts and folds it into a 3D model:"
Our system automatically constructs simple “pop-up” 3D models, like those one would find in a children’s book, out of a single outdoor image. The system labels each region of an outdoor image as ground, vertical, or sky. Line segments fitted to the ground-vertical boundary in the image and an estime of the horizon’s position provide the necessary information to determine where to “cut” and “fold” in the image. The model is then popped up, and the image is texture mapped onto the model.
