Automatic Photo Pop-Up

model from a single photograph. The model is made up of several
texture-mapped planar billboards and has the complexity of a
typical children’s pop-up book illustration. Our main insight is that
instead of attempting to recover precise geometry, we statistically
model geometric classes defined by their orientations in the scene.
Our algorithm labels regions of the input image into coarse categories:
“ground”, “sky”, and “vertical”. These labels are then used
to “cut and fold” the image into a pop-up model using a set of simple
assumptions. Because of the inherent ambiguity of the problem
and the statistical nature of the approach, the algorithm is not expected
to work on every image. However, it performs surprisingly
well for a wide range of scenes taken from a typical person’s photo
album.
