Statistical Noise Analysis for Motion Detection

摘要

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.

1. A machine-implemented method comprising:
calculating reference statistics related to one or more noise characteristics that correspond to a plurality of pixels in a first set of a plurality of video images of an area being monitored; receiving current noise characteristics that correspond to the plurality of pixels in a second set of one or more video images of the area being monitored, wherein the first set of video images were captured before the second set of video images; and detecting a motion in the area being monitored by comparing the reference statistics to the current noise characteristics.
