Interest Points
I learned a bit in a class called "Computer Vision".
One thing was "finding interest points".
Basically when you have a picture and give it to your computer it doesn't know anything what to do with it. It's just plain boring data. Every point is as interesting as every other. On some images you might have the same feeling. On others you recognize things which gives it more value then just color.
But what makes the difference?
How do you see something?
