Þýðing á "visual processing" í íslenska

4.1. A series of extrastriate visual areas continue the work of visual processing. Emerging from V1 (primary visual cortex, striate cortex) are two broad streams of processing: one going into the temporal lobe and the other into the parietal lobe. The temporal pathway seems specifically concerned with *what* a stimulus might be. This chapter follows that pathway. (The parietal *where* pathway will be considered in later chapters.) 4.2. After early visual processes extract basic features from the visual input, it is the job of mid-level vision to organise these features into the regions, surfaces, and objects that can, in turn, serve as input to object recognition and scene-understanding processes.

4.3. Perceptual “committees” serve as an important metaphor in this chapter. The idea is that many semi-independent processes are working on the input at the same time. Different processes may come to different conclusions about the presence of an edge or the relationship between two elements in the input. Under most circumstances, we see the single conclusion that the committees settle upon. Bayesian models are one way to formalise this process of finding the most likely explanation for input. Deep neural networks may be a way to build members/parts of the committee. 4.4. Multiple processes seek to carve the input into region and to define the edges of those regions, and many rules are involved in this parsing of the image. E.g., image elements are likely to group together if they are similar in colour or shape, if they are near each other, or if they are connected. Many of these grouping principles were first articulated by members of the Gestalt school.
