An algebraic cubature formula on curvilinear polygons
We implement in Matlab a Gauss-like cubature formula on bivariate domains whose boundary is a piecewise smooth Jordan curve (curvilinear polygons). The key tools are Green’s int...

An Efficiency Criterion for 2D Shape Model Selection.
We propose efficiency of representation as a criterion for evaluating shape models, then apply this criterion to compare the boundary curve representation with the medial axis. We...

A Subdivision Approach to Planar Semi-algebraic Sets
Abstract. Semi-algebraic sets occur naturally when dealing with implicit models and boolean operations between them. In this work we present an algorithm to efficiently and in a ce...

Boundary following by robot formations without GPS
— We design sensing algorithms and a control law for a group of mobile robots to follow a boundary curve without utilizing a global positioning system (GPS). The sensing algorith...
