Analogical representation of spatial events for understanding traffic behaviour
Richard J. Howarth, Hilary Buxton · 1992
. In computer vision the usual level of "interpretation " is the identification of the objects in the image. In this paper, we extend the level of interpretation to include spatial event detection using a knowledge base for a known scene. This will allow us to formulate a computational theory for forming conceptual descriptions about the behaviours of the objects. Here we describe an analogical representation of space and time that supports the formation of these conceptual descriptions and allows strong contextual indexing of our spatial knowledge. Keywords: Spatial representation, spatio-temporal reasoning, high-level vision, scene understanding. 1 Introduction This paper describes how spatial reasoning can be used to interpret the results from low-level vision, to obtain a greater understanding of what is going on in the field-of-view. This higher-level visual processing is able to reason over longer time scales because the data used is a condensed summary of the initial camera inp...
