Deformable surface matching as
Markov Random Field optimization
 Given two images,
estimate a mapping
from one image to
another providing
best visual
alignment.
 We apply discrete
approximation over
large search space.

Unmanned aerial
vehicle
•
The aim is the
detection of moving
vehicles on a
ground (speed 20150 km/h)
•
Compensation for
own UAV motion

 Developed on the Czech
Air Force demand of
from 2006 to 2008.
 Two CTU teams: Dept.
of Cybernetics and Dept.
of Control Engineering.
 Two feedbacks:
• the fast one dumps
vibrations of the UAV,
• the slow one tracks the
target.

 Does not loose
tracks when
the template is
not visible.
