A variational method with a noise detector for impulse noise removal
收藏 引用
1st international conference on scale space and variational methods in computer vision
作者: Chen, Shoushui Yang, Xin Shanghai Jiao Tong Univ Inst Image Proc & Pattern Recognit Shanghai 200030 Peoples R China
In this paper we propose a combined method for removing impulse noise. In the first phase, we use an efficient detector, called the statistics of Ordered Difference Detector (SODD) to identify pixels which are likely ... 详细信息

1st international conference on scale-space Theory in computer vision (scale-space 97)
作者: Faugeras, O Keriven, R INRIA Sophia Antipolis France MIT AI Lab Cambridge MA 02139 USA ENPC CERMICS Noisy Le Grand France
We present a novel geometric approach for solving the stereo problem for an arbitrary number of images (greater than or equal to 2). It is based upon the definition of a variational principle that must be satisfied by... 详细信息

Bounds on the minimizers of (nonconvex) regularized least-squares
收藏 引用
1st international conference on scale space and variational methods in computer vision
作者: Nikolova, Mila PRES UniverSud CNRS ENS Cachan CMLA F-94230 Cachan France
This is a theoretical study on the minimizers of cost-functions composed of an l(2) data-fidelity term and a possibly nonsmooth or non-convex regularization term acting on the differences or the discrete gradients of ... 详细信息

1st international conference on scale space and variational methods in computer vision
作者: Frick, Klaus Scherzer, Otmar Univ Innsbruck Dept Comp Sci Technikerstr 21A A-6020 Innsbruck Austria
Inverse scale space methods are derived as asymptotic limits of iterative regularization methods. They have proven to be efficient methods for denoising of gray valued images and for the evaluation of unbounded operat... 详细信息

Modeling foveal vision
收藏 引用
1st international conference on scale space and variational methods in computer vision
作者: Florack, Luc Eindhoven Univ Technol Dept Biomed Engn NL-5600 MB Eindhoven Netherlands
A geometric model is proposed for an artificial foveal vision system, and its plausibility in the context of biological vision is explored. The model is based on an isotropic, scale invariant two-form that describes t... 详细信息

1st international conference on scale space and variational methods in computer vision
作者: Tatu, Aditya Lauze, Francois Nielsen, Mads Olsen, Ole Fogh Univ Copenhagen DIKU Univ Sparken 1 DK-2100 Copenhagen Denmark Nordic Biosci Clin Stud AS Herlev 2370 Denmark IT Univ Copenhagen Copenhagen Denmark
Curve evolution forms the basis of active contour algorithms used for image segmentation. In many applications the curve under evolution needs to be restricted to the shape space given by some example shapes, or some ... 详细信息

1st international conference on scale space and variational methods in computer vision
作者: Overgaard, Niels Chr. Solem, Jan Erik Malmo Univ Appl Math Grp Sch Technol & Society Malmo Sweden
A variational formulation of an image analysis problem has the nice feature that it is often easier to predict the effect of minimizing a certain energy functional than to interpret the corresponding Euler-Lagrange eq... 详细信息

1st international conference on scale space and variational methods in computer vision
作者: Demetz, Oliver Weickert, Joachim Bruhn, Andres Welk, Martin Univ Saarland Fac Math & Comp Sci Math Image Anal Grp Bldg E1-1 D-66041 Saarbrucken Germany
Although variational models offer many advantages in image analysis, their successful application to real-world problems is documented only for some specific areas such as medical imaging. In this paper we show how we... 详细信息

A variational framework for the simultaneous segmentation and object Behavior classification of image sequences
收藏 引用
1st international conference on scale space and variational methods in computer vision
作者: Gui, Laura Thiran, Jean-Philippe Paragios, Nikos Ecole Polytech Fed Lausanne Signal Proc Inst Lausanne Switzerland Laboratoire MAS Ecole Centrale Paris France
In this paper, we advance the state of the art in variational image segmentation through the fusion of bottom-up segmentation and top-down classification of object behavior over an image sequence. Such an approach is ... 详细信息

1st international conference on scale space and variational methods in computer vision
作者: Besbes, Olfa Belhadj, Ziad Boujemaa, Nozha INRIA Rocquencourt IMEDIA Project F-78153 Le Chesnay France URISA SUPCOM Ariana Tunisia
In this paper, we present an adaptive variational segmentation algorithm of spectral / texture regions in satellite images using level set. Satellite images contain both textured and non-textured regions, so for each ... 详细信息
