Summary:In this paper we present a new Bayesian framework for partially
occluded object recognition with one-to-one correspondence. We introduce
two different statistical models for occlusion: One model assumes that
each feature in the model can be occluded independent of whether any
other features are occluded, whereas the second model uses spatially
correlated occlusion to represent the extent of occlusion. Using these
models, the object recognition problem reduces to finding the object
hypothesis with largest generalized likelihood We develop fast
algorithms for finding the optimal one-to-one correspondence between
scene features and object model features to compute the generalized
likelihood. We evaluate our algorithms using examples extracted from
synthetic aperture radar imagery, and illustrate the performance
advantages of our approach over alternative algorithms proposed by
others
