Detecting People with a Simple Webcam

Abstract

Imagine that you could not see the di erence between cars and the streets they move on. Crossing the street would be quite problematic. Luckily, visually identifying objects is an easy task for humans; we can almost instantly tell the di erence between two objects. For a computer, however, detecting or identi- fying objects has proven to be a di cult task [PP00]. A special form of visual object detection is people detection, which can be seen as object detection with only two classes of objects: human and non-human.
