Main Detection
-
In current ADVISOR System
- Amount of image area occupied by foreground ? estimate “crowding
level”. When greater than user limit ? overcrowding/blocking.
-
In future ADVISOR systems
- Amount of stationary foreground and the period of time it has been
stationary. When greater than a user-defined time ? stationarity.
- When the amount of foreground that is stationary is greater than a
user-defined value ? congestion.
- When amount of motion in a user-defined range of directions if greater
than a user-defined value ? counter-flow.
