Kalman filter application in video surveillance

Hello...

      I'm currently working on a project in video surveillance. After
performing foreground segmentation, I get blobs + noise (due to light
variation etc.). To separate the blobs from the noise, I perform simple
operations (such as removing all blobs with area < 500 pixels). I'm left
with blobs (humans and ghosts). Now here is my problem, how do I apply
kalman filters to track these blobs? Do I have to take into consideration
the acceleration? or can the input be simply x,y, velocity of x, velocity
of y? Thanks!
