A fundamental open problem in computer vision---determining pose and
correspondence between two sets of points in space---is solved with a novel,
fast, robust and easily implementable algorithm. The technique works on noisy
2D
or 3D point sets that may be of unequal sizes and may differ by non-rigid
transformations. Using a combination of optimization techniques such as
deterministic annealing and the softassign, which have recently emerged out of
the recurrent neural network/statistical physics framework, analog objective
functions describing the problems are minimized. Over thirty thousand
experiments, on randomly generated points sets with varying amounts of noise
and
missing and spurious points, and on hand-written character sets demonstrate the
robustness of the algorithm.
