Object separating algorithm based on background alternation and dynamic expanding filter
Jianwen Li · Computer Engineering and Applications Journal · 2010
Background subtraction is a method used mostly to get foreground objects in computer vision field;the keys of background subtraction are the building and updating of background and filtering of noises.The method based on background alternation needs a little of computation than the one based on statistic.Dynamic expanding filtering can do a little damage to the foreground objects and remove noises very well.When the camera is immobile,by using the methods mentioned,the foreground objects can be gotten clearly.
