Visualization

Abstract

To us, vision is an immediate experience, not subject to careful introspection. We cannot write down protocols of processing steps that lie between the raw image intensities and our vivid impression of the surrounding scenery. Furthermore, we find ourselves in possession of this faculty long before we learn to master the more sequential processing tasks involved in the use of language, for example. Consequently, the difficulties of the vision process are often not appreciated. This is as true today, when many inroads have been made on the problem of understanding this process, as it was earlier when it was thought that vision could be understood simply in terms of some general ideas of artificial intelligence.
