They down sampled by 2x, in other words, they just dropped half the pixel data. They then gave this half data to the algorithms. The full data was only used so they would have something to compare the output to.

How is that any different from just not capturing half the picture data? I don't see how it would be. You do realize a digital camera is just an array or sensors, right? What happens if your camera has half as many sensors? The same things as what they did, you have half as many pixels.
