Simulating CRF with CNN for CNN

no code implementations6 May 2019 Lena Gorelick, Olga Veksler

After our CRF Simulator is trained, it can be directly incorporated as part of any larger CNN architecture, enabling a seamless end-to-end training.

K-convexity shape priors for segmentation

no code implementations ECCV 2018 Hossam Isack, Lena Gorelick, Karin Ng, Olga Veksler, Yuri Boykov

As shown in the paper, for many forms of convexity our regularization model is significantly more descriptive for any given k. Our shape prior is useful in practice, e. g. in biomedical applications, and its optimization is robust to local minima.

Adaptive and Move Making Auxiliary Cuts for Binary Pairwise Energies

no code implementations CVPR 2017 Lena Gorelick, Yuri Boykov, Olga Veksler

First, unlike LSA-AUX which selects auxiliary functions based solely on the current solution, we propose to incorporate several additional criteria.

Efficient Squared Curvature

no code implementations CVPR 2014 Claudia Nieuwenhuis, Eno Toeppe, Lena Gorelick, Olga Veksler, Yuri Boykov

Curvature has received increasing attention as an important alternative to length based regularization in computer vision.

Submodularization for Binary Pairwise Energies

no code implementations CVPR 2014 Lena Gorelick, Yuri Boykov, Olga Veksler, Ismail Ben Ayed, Andrew Delong

We propose a general optimization framework based on local submodular approximations (LSA).

An Experimental Comparison of Trust Region and Level Sets

no code implementations8 Nov 2013 Lena Gorelick, Ismail BenAyed, Frank R. Schmidt, Yuri Boykov

High-order (non-linear) functionals have become very popular in segmentation, stereo and other computer vision problems.

Submodularization for Quadratic Pseudo-Boolean Optimization

no code implementations8 Nov 2013 Lena Gorelick, Yuri Boykov, Olga Veksler, Ismail Ben Ayed, Andrew Delong

We propose a general optimization framework based on local submodular approximations (LSA).

Efficient Regularization of Squared Curvature

no code implementations7 Nov 2013 Claudia Nieuwenhuis, Eno Toeppe, Lena Gorelick, Olga Veksler, Yuri Boykov

Curvature has received increased attention as an important alternative to length based regularization in computer vision.

Auxiliary Cuts for General Classes of Higher Order Functionals

no code implementations CVPR 2013 Ismail Ben Ayed, Lena Gorelick, Yuri Boykov

From these general-form bounds, we state various non-linear problems as the optimization of auxiliary functionals by graph cuts.

Fast Trust Region for Segmentation

no code implementations CVPR 2013 Lena Gorelick, Frank R. Schmidt, Yuri Boykov

In this paper we propose a Fast Trust Region (FTR) approach for optimization of segmentation energies with nonlinear regional terms, which are known to be challenging for existing algorithms.
