TLDR
A new approach to measuring the similarity of 3D curves is presented, based on an extension of the classical string edit distance that allows the possibility to use strings, where each element can be a vector rather than a single symbol.Abstract:
In this paper a new approach to measuring the similarity of 3D curves is presented. This approach is based on an extension of the classical string edit distance in two ways. The first extension is the possibility to use strings, where each element can be a vector rather than a single symbol, while the second extension is the use of fuzzy set based cost functions in the edit distance computation. These two extensions allow us to tackle various problems, that can't be solved by means of "classical" string edit distance.read more

3-Dimensional curve similarity using string matching
TL;DR: This paper presents a new approach to measuring the similarity between 3D-curves using the curvature and the tension as their symbolic representation, and allows the possibility of using strings, where each element is a vector rather than just a symbol.

Symmetry based indexing of diatoms in an image database
TL;DR: From the experimental results, it can be concluded that symmetry information is useful for various indexing tasks in image databases and the effort for the subsequent task of diatom classification can be reduced.
Patent
System for fingerprint authentication
TL;DR: In this paper, the length of arcs between starting measure point and ending measure points among every three consecutive measure points on the curve is defined as the data of lengths of arcs that connect the starting and ending points of a curve.
