Comparison between Architectures and Data
Independency

Table 2 summarizes comparison results between different architectures dis-
cussed. Among all the architectures, the symmetric parallel architecture can
provide the better speed-up, while the pipelining architecture will be able to
reduce hardware effort on processors. As we can see through our discussion,
those different architectures do not mutually exclude each other. Thus, we would
expect a better solution by combining them together.

Discussion on Multiple Camera Systems

In this subsection, we examine the parallelism architecture aspects of the 3D
camera system. Figure 23 shows the algorithm stages in the system. Figure 24
shows the processing time for each algorithm stage.
