Version v2.2.2 - Minor update
What's new:
Just change blob.Center information for Kalman blobie - d30f216
old:
b.Track = append(b.Track, newbCast.Center)
new:
b.Track = append(b.Track, b.Center)
This change is needed due the DrawTrack() and PredictNextPosition() functions since thouse functions uses not only rectangle, but centroids too.
