First Claim
Patent Images
1. A method for processing video, comprising the steps of:
- maintaining a background model for said video;
detecting a target in said video;
detecting if said target is a stationary target; and
classifying said stationary target as an insertion in said background model or a removal from said background model.

Abstract
Video is processed by maintaining a background model for the video, detecting a target in the video, detecting if the target is a stationary target, and classifying the stationary target as an insertion in the background model or a removal from the background model.

13. A computer system for processing video, comprising:
-
a background model of said video;
a background model-based pixel classification to produce a change mask and imagery based on said video and said background model;
a background model update to update said background model based on said change mask and said imagery;
a motion-based pixel classification to produce a motion mask based on said video;
a blob generation to produce at least one blob based on said change mask and said motion mask;
a blob tracking to produce at least one target based on said blobs;
a stationary target detection and classification to produce a stationary target description based on each target, said stationary target description to identify each said target as an insertion in said background model or a removal from said background model; and
a background model local update to update said background model based on each said stationary target description. - View Dependent Claims (14, 15)
