Hamiltonian operator for spectral shape analysis

Y Choukroun, A Shtern, A Bronstein… - IEEE transactions on …, 2018 - ieeexplore.ieee.org
Many shape analysis methods treat the geometry of an object as a metric space that can be
captured by the Laplace-Beltrami operator. In this paper, we propose to adapt the classical …

[HTML][HTML] Matching the LBO eigenspace of non-rigid shapes via high order statistics

A Shtern, R Kimmel - Axioms, 2014 - mdpi.com
A fundamental tool in shape analysis is the virtual embedding of the Riemannian manifold
describing the geometry of a shape into Euclidean space. Several methods have been …

Spectral gradient fields embedding for nonrigid shape matching

A Shtern, R Kimmel - Computer Vision and Image Understanding, 2015 - Elsevier
A popular approach for finding the correspondence between two nonrigid shapes is to
embed their two-dimensional surfaces into some common Euclidean space, defining the …

Iterative closest spectral kernel maps

A Shtern, R Kimmel - 2014 2nd International Conference on 3D …, 2014 - ieeexplore.ieee.org
An important operation in geometry processing is finding the correspondences between pairs
of shapes. Measures of dissimilarity between surfaces, has been found to be highly useful …

Fast blended transformations for partial shape registration

A Shtern, M Sela, R Kimmel - Journal of Mathematical Imaging and Vision, 2018 - Springer
Automatic estimation of skinning transformations is a popular way to deform a single reference
shape into a new pose by providing a small number of control parameters. We generalize …

[PDF][PDF] V-Flow: Deep Unsupervised Volumetric Next Frame Prediction

A Shtern, R Kimmel - academia.edu
Predicting the temporal dynamics of threedimensional images is an important means for
analyzing volumetric data. We propose an unsupervised learning of a multi-scale optical flow …

On Nonrigid Shape Similarity and Correspondence

A Shtern, R Kimmel - arXiv preprint arXiv:1311.5595, 2013 - arxiv.org
An important operation in geometry processing is finding the correspondences between
pairs of shapes. The Gromov-Hausdorff distance, a measure of dissimilarity between metric …

Workshop 2 Keynote Address 2

A Shtern - ieeexplore.ieee.org
Recent years have witnessed a growing number of different descriptors for various shape
analysis tasks. These methods, inspired by their computer-vision counterparts, strive to capture …

Oviposition habitat selection by Anopheles gambiae in response to chemical cues by Notonecta maculata

A Warburg, R Faiman, A Shtern… - Journal of Vector …, 2011 - Wiley Online Library
A number of mosquito species avoid predator‐inhabited oviposition sites by detecting
predator‐released kairomones. In the laboratory, we found that when offered de‐ionized water …

[HTML][HTML] Long-term impact of phosphorous fertilization on yield and alternate bearing in intensive irrigated olive cultivation

A Haberman, A Dag, R Erel, I Zipori, N Shtern… - Plants, 2021 - mdpi.com
Phosphorus (P) availability significantly impacts olive tree reproductive development and
consequential fruit production. However, the importance of P fertilization in olive cultivation is …
