The final report of a two-year study concerned with the digital-computer processing of graphical data. Five separate investigations carried out under this study are described briefly, and a detailed bibliography, complete with abstracts, is included in which are listed the technical papers and reports published during the period of this program. The investigations consisted of (1) a study of a linguistic approach to pattern recognition, (2) the optimum two-dimensional allocation problem, (3) the hidden-line problem for quadricsurfaced solids, (4) the reconstruction problem for irregular polyhedra, and (5) the data-structure problem for computer graphics.
