[M4IF Technotes] Motion Estimation

[Prabhudev Hosur]

Hi,
You can design your own motion estimation algorithm for obtaining the
motion vector.  So you may use your own bias value for SAD(0,0), which
you think is the best bias value.

SAD(0,0) - (N_b / 2 +1)
formula is used in the VM18.0 to get the SAD(0,0) value.
It is counter-intuitive for N_b to be related to the VOP. I would espect
it 
to be related to the number of elements being summed up in the SAD(x,y) 
calculation.
Can someone point me to any literature or web-sites, where this
subtracted 
number, namely, N_b/2+1 is justified?
Thanks
Arcin
