Sometimes the eﬀects are dramatic, to the point that the viewer can make no sense of the image at all until, when cued with a single word, the object pops out of the image. 1. 1: Priming with prior knowledge. If you have never seen it before this ﬁgure probably means little at ﬁrst sight. Now look for a cyclist in a Mexican hat. rather “high-level,” calling on some intricate and diverse common-sense knowledge concerning wheels, hats and so on. The aim of this book is to look at how prior 2 Chapter 1 knowledge can be applied in machine vision at the lower level of shapes and outlines.

This has two great advantages. First there is no need to organise or group features in the image; the relevant area of the image is simply tested directly against its expected appearance. Secondly, the fact that analysis can be restricted to a relatively narrow “region of interest” (around the road edge) eases the computational load. Active Vision, then, uses task-related prior knowledge to simplify and focus the processing that is applied to each image. This book is concerned with the application of prior knowledge of a particular kind, namely geometrical knowledge.
