Abstract

The goal of the work here reported is to Investigate algorithms which find the real straight edges In scenes consisting of prismatic solids, taking Into account smooth variations In Intensity over faces, blurring of edges, and noise. To this end we give In thts paper a model of the appearance to an optical Input device of such scenes; and describe a sub-optimal statistical decision procedure, based on the model, for the Identification of a line within a narrow band on the field of view, given an array of Intensities from within the band.
