•Sum a different distance
–f(d) = d2
–or Manhattan
distance.
–f(d) = 1 if d <
threshold, 0 otherwise.
–This is called bounded
error.
•Use maximum distance instead of sum.
–This is called: directed
Hausdorff distance.
–Use median distance.
•Use other features
– Corners.
–Lines. Then
position and angles of lines must be similar.
•Model line may be subset of image line.
