Exercises 289

Use probabilistic relaxation in order to classify an "unknown" image as one of these
prototypes. For this purpose, consider each tank described by two rectangular regions,
as shown in the Figure above, and use the image registration approach described in
section 6.4.2. As an alternative to the area of each region use the ratio llw, where I and
w are respectively the length and width of a rectangular region.
6.23 Consider the prototype drawing of Figure 6.23. Use the HopJeld program in order to
determine the compatible assignments with the line drawings in the Figure below.

6.24 Use the Hopfield program in order to determine the homomorphisms for the graphs
shown in Figure 6.28. Compare the results obtained with those of Table 6.7.
