Affine Matching with Bounded Sensor Error: A Study of Geometric Hashing and Alignment
Grimson W. Eric L.; Huttenlocher, Daniel P.; Jacobs, David W. (1991-08-01)Affine transformations are often used in recognition systems, to approximate the effects of perspective projection. The underlying mathematics is for exact feature data, with no positional uncertainty. In practice, ... -
Object Recognition By Alignment Using Invariant Projections of Planar Surfaces
Nagao, Kanji; Grimson W. Eric L. (1994-02-01)In order to recognize an object in an image, we must determine the best transformation from object model to the image. In this paper, we show that for features from coplanar surfaces which undergo linear transformations ...
