5.2.3
The following presents some experiments. Given a number of model
objects, a scene is generated. Properties and relations in model
objects and the scene are measured using the same program. Only the
second order energy 
is taken into consideration. The energy is
minimized by using a relaxation labeling algorithm
(see Section 8.2.2). In the computation of the minimal
solution, interactions or compatibilities are represented by integers of
only 8 bits and good results are achieved; this demonstrates the
error-tolerant aspect of the model. The optimal matching result is
displayed by aligning the matched object features to the scene while the
unmatched are not displayed. The alignment is performed between the
matched pairs by using the least squares fitting method
[Umeyama 1991]. Parameters 
is fixed for all the
experiments. Parameters 
vary for different
applications.
