[4eyes] interesting paper: visual motion estimation with a single point correspondance

[Steffen Gauglitz]

FYI:
interesting paper on using a single point correspondance to estimate the 
motion of a wheeled vehicle:

(of course, more than one correspondence could and should be used, but 
structurally, the outlier removal becomes a lot simpler for a 
two-dimensional parameter vector!)
