Synthetic Signals and Images
When testing new algorithms, it is often useful to start experiments using synthetic data for which the result of the processing is known (c.f. Sect.3.2). Image synthesis is part of computer graphics (c.f. Sect. 1.1), and also the generation of realistic speech signals using text input is an area of research. In this chapter we mostly establish regular patterns or global features which are useful in pattern recognition for testing low—level algorithms.
