Abstract
An approach is provided to detecting motion using statistical noise analysis. In the approach, reference statistics are calculated that relate to one or more noise characteristics that correspond to pixels in a first set of video images of an area being monitored. Current noise characteristics are received that correspond to the same pixels in a second set of video images of the area being monitored, with the first set of video images being captured before the second set of video images. Motion is detected in the area being monitored by comparing the reference statistics to the current noise characteristics.
