A Note on the Computation of Binocular Disparity in a Symbolic, Low-Level Visual Processor

  • David Marr


The goals of the computation that extracts disparity from pairs of pictures of a scene are defined, and the constraints imposed upon that computation by the three-dimensional structure of the world are determined. Expressing the computation as a gray-level correlation is shown to be inadequate. A precise expression of the goals of the computation is possible in a low-level symbolic visual pro- cessor: the constraints translate in this environment to prerequisites on the binding of disparity values to low-level symbols. The outline of a method based on this is given.
