We have developed several theorems for the detection of parallel curve
s in the continuous space. In this paper, we studied issues in carryin
g the continuous algorithm to the discrete case and also the perceptua
l characteristics leading to human recognition of parallelism. By form
ulating these properties in terms of several distinctive forces, we de
veloped a force-driven model as a new optimization strategy to perform
correspondence establishment between points in the matching curves. T
his force-driven mechanism provides a good coupling (or correspondence
matching) result, which is the prerequisite for the correct detection
of parallelism between curves. Convergence of the algorithm and imple
mentation efficiency are also investigated and discussed. Experimental
results on the relative weightings of these forces also shed light on
the perceptual priority imposed by the human vision system. (C) 1997
