Hypothesis Verification

The model invocation and hypothesis construction processes are largely based on processing symbolic structural descriptions and do not closely examine the input data. Further, tolerances are allowed in the matching process to overcome noise, segmentation variations and imperfect descriptive processes. Consequently, it is possible for coincidental scene arrangements to lead to spurious object hypotheses. Many of these false hypotheses will have been eliminated by the geometric constraints examined during hypothesis construction, but some may remain. This chapter discusses additional constraints on solid physical objects that help guarantee object existence and identity.
