We present a method for the exact computation of the moments of a region bounded by a curve represented by a scaling function or wavelet basis. Using Green's Theorem, we show that the computation of the area moments is equivalent to applying a suitable mul ...
In this work, we present a novel way of computing the continuous Haar, Fourier and cosine series coefficients of rectilinear polygons. We derive algorithms to compute the inner products with the continuous basis functions directly from the vertices of the ...
Multiphase variable-speed drives, supplied from two level voltage-source inverters (VSIs), are currently considered for a number of industrial applications. Although various multiphase pulsewidth-modulated (PWM) schemes had been recently developed, very li ...
We present a new scheme for digital watermarking of point-sampled geometry based on spectral analysis. By extending existing algorithms designed for polygonal data to unstructured point clouds, our method is particularly suited for scanned models, where th ...
The 2-D Laguerre model of the grain growth process as the evolution of a simple convex polygonal complex is generalized to the case of a heterogeneus system. Due to the existence of several types of grains in the system, the specific grain boundary energy ...
We present an exact algorithm for the computation of the moments of a region bounded by a curve represented in a scaling function or wavelet basis. Using Green's theorem, we show that the computation of the area moments is equivalent to applying a suitable ...
We present a simple constructive heuristic for the optimal enclosed area polygon problem. Namely, given a finite set S of points in the plane, we look for the simple polygon with vertex set S having minimal, respectively maximal, enclosed area. ...
Many known materials possess polycrystalline structure. The images produced by plane cuts through such structures are polygonal complexes. The problem of finding the edges, when only the vertices of a given polygonal complex are known, is considered. A com ...
