1 Introduction

This chapter addresses the status of the vision architectures in four major fields: computer architectures, vision algorithms, vision devices, and design methodologies. Computer architecture, which is characterized by serial, parallel, pipelined, and concurrent computation, must be tuned to the underlying computational structures – parallel, iterative, and neighborhood computation – that are used in intermediate computer vision. Vision algorithms, which have evolved from heuristic methods to generic structured algorithms at each level of computer vision from low level to high level, must be investigated in terms of computational structures. The vision devices, ranging from CPUs to very-large-scale integration (VLSI) chips, must be investigated in terms of their flexibility and computational complexity. Finally, the design flow from vision to chip, which is not well-defined, must be defined and delineated using a general methodology.

1.1 Computer Architectures for Vision

Vision architectures are special forms of more general computer architectures. In the early 1970s, a general point of view on computer architecture was to see it as an information flow of data and instructions into a processor (Figure 1.1). Flynn's taxonomy (Flynn 1972) is the most universally accepted method of classifying computer systems. The instruction stream is defined as the sequence of instructions performed by the processing unit. The data stream is defined as the data traffic exchanged ...
