Collecting Trash: A Test of Purposive Vision

The purposive approach to computer vision has been much discussed in recent years, but there have been few tests of the viability of the paradigm in a working vision system. We have tested the approach in the context of vision for a mobile robot performing tasks in a typical, unaltered o ce environment. In particular, we examine the approach in the context of a trash collection task; the task t...

Affine Surface Reconstruction by Purposive Viewpoint Control

We present an approach for building an affine representation of an unknown curved object viewed under orthographic projection from images of its occluding contour. It is based on the observation that the projection of a point on a curved, featureless surface can be computed along a special viewing direction that does not belong to the point’s tangent plane. We show that by circumnavigating the ...

Meta-language utterances in purposive discourse

Meta-language utterances, i.e. utterances about other utterances, are ubiquitous in every type of human discourse, from unconstrained multi-party conversations to task-oriented man-machine dialogues. Several examples of meta-language communication are analyzed, identifying the complexities that a cognitively plausible discourse model should address. Meta-language utterances are investigated in ...
