Reliable online monitoring of wear remains a challenge to tribology research as well as to the industry. This paper presents a new method for monitoring of dry sliding wear using digital imaging and fractal analysis. Fractal values, namely fractal dimension and intercept, computed from the power spectrum of the images of a wearing surface, are adopted as(More)
We propose a technique that combines geometric hashing with stereo vision. The idea is to use the robustness of geometric hashing to spurious data to overcome the correspondence problem, while the stereo vision setup enables direct model matching using the 3-D object models. Furthermore, because the matching technique relies on the relative positions of(More)
In this paper we compare our 3-D geometric hashing approach to object recognition to a 2-D geometric hashing approach developed by Gavrila and Groen. We apply both methods to same recognition task using real images. We found that the indexing technique used in geometric hashing is much more eecient in the 3-D case than it is in the 2-D case. Furthermore,(More)
