The ordering constraint along epipolar lines is a |
|
powerful constraint that has been exploited by some |
|
recent stereomatching algorithms. We formulate a |
|
generalized ordering constraint, not restricted to |
|
epipolar lines. We prove several properties of the |
|
generalized ordering constraint and of the forbidden zone |
|
, the set of matches that would violate the constraint. |
|
We consider both the orthographic and the perspective |
|
projection case, the latter for a simplified but standard |
|
stereo geometry. The disparity gradient limit found in |
|
the human stereo system may be related to a form of the |
|
ordering constraint. To illustrate our analysis we |
|
outline a simple algorithm that exploits the generalized |
|
ordering constraint for matching contours of wireframe |
|
objects. We also show that the use of the generalized |
|
ordering constraint implies several other stereo matching |
|
constraints: (a) the ordering constraint along epipolar |
|
lines, (b) figural continuity, (c) Binford's cross- |
|
product constraint, (d) Mayhew and Frisby's figural |
|
continuity constraint. We finally discuss ways of |
|
extending the algorithm to arbitrary 3-D objects. |
