Incorporating Object Tracking Feedback into Background Maintenance Framework [PDF]

2005 Seventh IEEE Workshops on Applications of Computer Vision (WACV/MOTION'05) - Volume 1, 2005
Adaptive background modeling/subtraction techniques are popular, in particular, because they are able to cope with background variations that are due to lighting variations. Unfortunately these models also tend to adapt to foreground objects that become stationary for a period of time; as a result such objects are no longer considered for further ...
