Average task times in usability tests: what to report?
The distribution of task time data in usability studies is positively skewed. Practitioners who are aware of this positive skew tend to report the sample median. Monte Carlo simul...

Test and Measure of Circularity for Digital Curves
We propose one geometric algorithm to solve both the problem of circularity test and the problem of circularity measure. The former problem consists in deciding whether a given di...

A comparison of Gaussian and mean curvatures estimation methods on triangular meshes
Estimating intrinsic geometric properties of a surface from a polygonal mesh obtained from range data is an important stage of numerous algorithms in computer and robot vision, co...

Automatic Verification of Regular Constructions in Dynamic Geometry Systems
We present an application of an automatic theorem proving (ATP) in the verification of constructions made with dynamic geometry software (DGS). Given a specification language for g...

A Deductive Database Approach to Automated Geometry Theorem Proving and Discovering
We report our effort to build a geometry deductive database, which can be used to find the fixpoint for a geometric configuration. The system can find all the properties of the con...
