Development of a New Technique for Image Reconstruction, Enhancement, and Visualization

Abstract

The problem of describing and reconstructing a surface, both analytically and visually been extensively addressed in this work. Various algorithms have been developed, tested, and compared and several conclusions have been reached. They are: (1) if the surface information is given on a uniform grid, the surface is best described by a set of contour plotting routines that exploit the GL graphics libraries both in a solid as well as a wire-mesh framework; (2) if the surface information is given on a non-uniform grid, the surface can be described by Delaunay triangulation, a sophisticate graphics computer, or by interpolation back to a uniform grid. Numerous examples are given which show the advantages of these methods for specific applications.
