Free-Form Surface Matching for Surface Inspection

Free-Form Deformation for Point-Sampled Surface

In this paper, we present a free-form deformation (FFD) approach to manipulate point-sampled surface. Our approach provides users the powerful free-form deformation directly on point-sampled surface. In the preprocessing, we use a robust extension of hierarchical clustering scheme to partition a point-sampled model into clusters, fit a moving least square (MLS) surface to each of them, and defi...

Genetic algorithms for free-form surface matching

The free-form surface matching problem is important in several practical applications, such as reverse engineering. An accurate, robust and fast solution is, therefore, of great significance. Recently genetic algorithms have attracted great interest for their ability to robustly solve hard optimization problems. In this work we investigate the performance of such an approach for finding the ini...

Free-Form Surface Registration using Surface Signatures

This paper introduces a new free-form surface representation scheme for the purpose of fast and accurate registration and matching. Accurate registration of surfaces is a common task in computer vision. The proposed representation scheme captures the surface curvature information, seen from certain points and produces images, called surface signatures, at these points. Matching signatures of di...
