Member Function Documentation

Given a list of representations which describe the underlying real world object, assigns probabilities for each representation that the representation is the best description of the real object.

The probability that the object represented by the cluster is even in the database is (hopefully) the probability that the object matches the best model fit. Therefore, all of the model probabilities each get some share of the probability that the object is in the DB. The rest of the probability goes to model id -1, which is the probability that it is NOT in the DB (and therefore we should use the cluster grasp planner).

Assign the rest of the probability to the hypothesis "not in DB" for use by cluster planner
