Machine Recognition as Representation and Search
(1989-12-01)
Generality, representation, and control have been the central issues in machine recognition. Model-based recognition is the search for consistent matches of the model and image features. We present a comparative ...
The Combinatorics of Heuristic Search Termination for Object Recognition in Cluttered Environments
(1989-05-01)
Many recognition systems use constrained search to locate objects in cluttered environments. Earlier analysis showed that the expected search is quadratic in the number of model and data features, if all the data comes ...
A Modern Differential Geometric Approach to Shape from Shading
(1989-06-01)
How the visual system extracts shape information from a single grey-level image can be approached by examining how the information about shape is contained in the image. This technical report considers the characteristic ...
