A Survey of Methods to Extract Buildings from High-Resolution Satellite Images

There are many things in this world that are simply amazing. Some of these things are crafted by nature, such as the mighty Grand Canyon, the luscious rain forests of the tropics, and even a tiny flower on a high mountain top trying to send its roots down through cracks in the rock. Some things are also manmade, the Great Pyramids of Egypt, the Taj Mahal, and the Sistine Chapel all come to mind. While all these things are amazing in their own right, there might be something going on behind the scenes that is even more amazing. I am of course talking about the power of human vision, the ability we have that lets us easily comprehend patterns, colors, and shapes. It is not until I started looking into the field of computer vision that I realized what makes humans be able to comprehend images and scenes with little thought, is not as trivial or as simple as it may seem.
