A Unified Paradigm: Complex Systems

In this chapter, the flexibility and extensibility of the Unified Paradigm will be demonstrated in two example applications, both of which are considerably more complex than those studied in the preceding chapter. These examples will show that with the use of appropriate color encoding specifications, powerful systems can be assembled by linking simpler system components and subsystems in various parallel and serial arrangements. Also in this chapter the concept of image states will be introduced, and the principles and methodologies of scene-based color encoding and output rendering will be explored further.

A comprehensive color-imaging system

The requirements for the first example system, illustrated in Figure 21.1, might seem quite daunting because they include support for a diverse array of input and output media, devices, and image interpretations. On closer inspection, however, it can be seen that these specifications can be realized simply by combining the individual example systems previously described in Chapter 20 into a single system based on a common CES. Anticipation of this example was the reason an identical CES was used in all of the examples of that chapter.

As Figure 21.1 shows, the component inputs and outputs are both organized in parallel arrangements. With this strategy, images from any input medium, input device, and input-image interpretation can be transformed to the CES using appropriately selected input transformation ...
