Abstract
A visual object detection system to provide access and/or presence monitoring of an area of interest. In steady state operation, that is when no object is entering or within the area of interest, only those portions of the incoming images that correspond to the border of the area of interest are analyzed. Once the border is breached by an object, the present invention may begin analyzing the entire area or selected regions inside the border of the area of interest. This may provide some level of presence monitoring of the area of interest. It is contemplated that both modes of analysis can take place simultaneously or sequentially, depending on the application. Once the object leaves the area of interest, the present invention preferably returns to the original steady state, and monitors only the border regions of the incoming images.

27. A system for monitoring an area of interest having a border and an interior region, comprising:
-
capturing means for capturing a capture image of the area of interest; and
monitoring means for monitoring at least a portion of the border region of the area of interest for breach by an object, and for monitoring at least a portion of the interior region of the area of interest for the presence of the object after the object breaches the border.

28. A system for monitoring an area of interest, comprising:
-
image capturing means for capturing at least one image of the area of interest;
first processing means for processing at least one of the capture images to determine if an object has entered the area of interest;
second processing means for processing at least one of the capture images to determine if an object has entered the area of interest; and
output means for outputting a signal indicating that an object has entered the area of interest when both the first processing means and second processing indicate that an object has entered the object of interest.

31. A method for monitoring an area of interest having a border region and an interior region, the method comprising the steps of:
-
monitoring at least a portion of the border region of the area of interest for breach by an object having a first minimum size; and
monitoring at least a portion of the interior region of the area of interest for an object having a second minimum size after the object breaches the border region of the area of interest. - View Dependent Claims (32, 33, 34, 35, 37, 38, 39, 40, 41)
