On the error analysis of 'geometric hashing'

Proceedings. 1991 IEEE Computer Society Conference on Computer Vision and Pattern Recognition, 2002
An experimental and theoretical analysis of the noise model in the geometric hashing technique is presented. The efficacy of the technique is discussed in the cases of affine transformations, similarities, and grid motions. The efficacy of the voting procedure, in geometric hashing is discussed, and it is shown that its introduction significantly ...

Error propagation in geometric constructions

Computer-Aided Design, 2000
In this paper we consider error propagation in geometric constructions from a geometric viewpoint. First we study affine combinations of convex bodies: this has many applications concerning spline curves and surfaces defined by control points. Second, we study in detail the circumcircle of three points in the Euclidean plane.
