Figure 4. Part of an AIMS image imposed with extracted regions. Exterior orientation parameters
of the image are obtained by GPS and INS.
4. TRUCK RECOGNITION USING TWO LAYER
HOPFIELD NEURAL NETWORK
Figure 4 illustrates an AIMS (Airborne Integrated Mapping
System) image from which trucks moving on a freeway are to
be recognized. The height of a truck is relatively small in
comparison to the flying height so that the top of the truck
appears as a relatively light region in the image. It is clear that
the truck’s shadow plays an important role in telling whether or
not a region belongs to a truck. Given the interior and exterior
orientation parameters of the image along with an approximate
elevation value of the freeway, we could back-project a 3-D
model of the truck as well as it’s shadow to the image. The
trucks and their shadows don not change much in terms of site
and shape. This allows us to match extracted regions (truck
top) with the back-projected model directly. The shadows,
unfortunately, differ from one to another. Some trucks may not
have complete shadows. A two-layer Hopfield network
recognizes not only the regions similar to the back-projected
model without shadows but also those not very similar to the
model with strong support of shadows. The relationship
between each pair of regions (potentially a truck top with its
shadow) and the edges is examined by the two-layer Hopfield
network simultaneously.

neurons are listed in Table 1.

Table 1. Extracted neuron states of the two-layer network. The
shaded cells mean that the corresponding line or region
matches with the model feature. Note: Line Ids are not shown
in Figure 5.
The network recognized 10 out of 12 trucks in the entire image.
Figure 5 illustrates two recognized trucks. In Figure 5(a) the
extracted edges and regions are of high quality. Region 74
describing the top of the truck matches with the model top and
the adjacent region 265 describing its shadow matches with the
shadow of the model (Table 1). The edges of Region 74 match
