Multiresolution Jet Reconstruction with FFTJet

FFTJet: A Package for Multiresolution Particle Jet Reconstruction in the Fourier Domain

This article describes the FFTJet software package designed to perform jet reconstruction in the analysis of high energy physics (HEP) experimental data. A two-stage approach is adopted in which pattern recognition is performed first, utilizing multiresolution filtering techniques in the frequency domain. Jet energy reconstruction follows, conditional upon the choice of signal topology. The met...

Multiresolution discontinuity-preserving surface reconstruction

This paper proposes a single multiresolution framework for both surface "tting and discontinuities identi"cation in the surface reconstruction problem. In particular, the Mallat}Zhong wavelet transform modulus maxima (WTMM) representation is employed for representing the surface which allows the discontinuity detection and surface "tting to be carried out simultaneously in a cooperative manner ...

Reconstruction of Multiresolution Terrain Surfaces

Multiresolution surfaces are especially useful for fast rendering, real-time display and interactive manipulation of large and dense terrain surface models. This paper reviews major multiresolution terrain surface reconstruction techniques and analyses the corresponding data structures. We have proposed and implemented, based on Delaunay retriangulation, a greedy refinement algorithm with a str...

Multiresolution image acquisition and surface reconstruction

This paper is concerned with the problem of surface reconstruction from stereo images for large scenes having large depth ranges, where it is necessary to aim cameras in different directions and to fixate at different objects. In the past we have reported an approach to acquiring multiresolution surface information. This paper concentrates on the selection of new fixation points from among the ...
