Verification is the final decision stage in many object recognition pr
ocesses. It is carried out by evaluating a score for every hypothesis
and choosing the hypotheses associated with the highest score. This pa
per suggests a grouping-based verification paradigm, relying on the ob
servation that a group of data features belonging to a hypothesized ob
ject instance should be a ''good group.'' Therefore, it should support
perceptual grouping information available from the image by grouping
relations. The proposed score, which is the joint likelihood of these
grouping cues, quantifies this observation in a probabilistic framewor
k. Experiments with synthetic and real images show that the proposed m
ethod performs better in difficult cases.
