Variational Autoencoding of Dental Point Clouds
Johan Ziruo Ye, Thomas Ørkild, Peter Lempel Søndergaard +1
Digital dentistry has made significant advancements, yet numerous challenges remain. This paper introduces the FDI 16 dataset, an extensive collection of tooth meshes and point clo…
A multi-patient analysis of the center of rotation trajectories using finite element models of the human mandible
Torkan Gholamalizadeh, Sune Darkner, Peter Lempel Søndergaard +1
Studying different types of tooth movements can help us to better understand the force systems used for tooth position correction in orthodontic treatments. This study considers a…
A Non-iterative Method for (Re)Construction of Phase from STFT Magnitude
Zdeněk Průša, Peter Balazs, Peter L. Søndergaard
A non-iterative method for the construction of the Short-Time Fourier Transform (STFT) phase from the magnitude is presented. The method is based on the direct relationship between…
Designing Gabor windows using convex optimization
Nathanaël Perraudin, Nicki Holighaus, Peter L. Søndergaard +1
Redundant Gabor frames admit an infinite number of dual frames, yet only the canonical dual Gabor system, constructed from the minimal l2-norm dual window, is widely used. This win…
Efficient algorithms for discrete Gabor transforms on a nonseparable lattice
Christoph Wiesmeyr, Nicki Holighaus, Peter L. Soendergaard
The Discrete Gabor Transform (DGT) is the most commonly used transform for signal analysis and synthesis using a linear frequency scale. It turns out that the involved operators ar…
The Pole Behaviour of the Phase Derivative of the Short-Time Fourier Transform
Peter Balazs, Dominik Bayer, Florent Jaillet +1
The short-time Fourier transform (STFT) is a time-frequency representation widely used in applications, for example in audio signal processing. Recently it has been shown that not…
Iterative algorithms to approximate canonical Gabor windows: Computational aspects
A. J. E. M. Janssen, Peter L. Soendergaard
In this paper we investigate the computational aspects of some recently proposed iterative methods for approximating the canonical tight and canonical dual window of a Gabor frame…
