Abstract
A system for detecting a motion event based on images. The system acquires a first image and a comparison image, and generates a first edge image and a comparison edge image based on the first image and the comparison image. The system also determines the difference between the first edge image and the comparison edge image. The system indicates a motion event if the difference between the first edge image and the comparison edge image meets or exceeds a threshold.
