Computer vision (or image understanding) is generally defined as the construction of explicit, meaningful descriptions of the structure and the properties of the three-dimensional world from two-dimensional images. A conceptual framework for image understanding that is widely accepted is based on Marr’s concept of visual perception as computational process (Marr 1982). Marr postulated a hierarchical architecture for vision systems with different intermediate representations and processing levels (low, middle, and higher level vision). The methodology introduced by Marr — description of cognitive processes on the levels of computational theory, algorithm, and implementation — serves as a guideline, even today, for the “classica”, symbolic AI and the cognitivist paradigm of Cognitive Science, respectively.
