• Extracting a Valid Boundary Representation From a Segmented Range Image,
  Adam W. Hoover, Dmitry Goldgof, and Kevin W. Bowyer.
  IEEE Transactions on Pattern Analysis and Machine Intelligence 17, (9), 920-924, September 1995.
  "A new approach is presented for extracting an explicit 3-D shape model from a single range image. One novel aspect is that the model represents both observed object surfaces, and surfaces which bound the volume of occluded space. Another novel aspect is that the approach does not require that the range image segmentation be perfect. ... A third novel aspect of this work is that the implementation has been evaluated on over 200 real images of polyhedral objects with no operator intervention and all parameters held constant, and obtained a 97% success rate in creating valid b-reps."
  

• The Scale Space Aspect Graph,
  David W. Eggert, Kevin W. Bowyer, Charles R. Dyer, Henrik I. Christensen, and Dmitry B. Goldgof.
  IEEE Transactions on Pattern Analysis and Machine Intelligence 15 (11), 1114-1130, November 1993.
  "This paper introduces the concept of the scale space aspect graph, defines three different interpretations of the scale dimension, and presents a detailed example for a simple class of objects, with scale defined in terms of the spatial extent of features in the image."
  

• Computing the Generalized Aspect Graph for Objects with Moving Parts,
  Kevin W. Bowyer, Maha Y. Sallam, David Eggert, and John H. Stewman,
  IEEE Transactions on Pattern Analysis and Machine Intelligence 15 (6), 605-610, June 1993.
  "A number of researchers have described algorithms for computing the aspect graph representation, but this work has thus far been limited to entirely rigid objects. We generalize this concept to include a larger, more realistic domain of objects known as articulated assemblies, those objects composed of rigid parts with articulated connections allowed between parts."
  

• Computing the Perspective Projection Aspect Graph of Solids of Revolution,
  David W. Eggert and Kevin W. Bowyer,
  IEEE Transactions on Pattern Analysis and Machine Intelligence 15 (2), 109-128, February 1993.
  "This paper presents the first (only) implemented algorithm to compute the aspect graph for a class of curved-surface objects based on an exact parcellation of 3-D viewpoint space. The class of objects considered is solids of revolution. ... the worst-case complexity of ... the number of cells in the aspect graph is is O(N^4), where N is the degree of a polynomial that defines the object shape."
