Implicit Meshes for Effective Silhouette Handling
Authors: Slobodan Ilić, Mathieu Salzmann, Pascal Fua
Venue: International Journal of Computer Vision (2007)

Using silhouettes in uncontrolled environments typically requires handling occlusions as well as changing or cluttered backgrounds, which limits the applicability of most silhouette based methods. For the purpose of 3-D shape modeling, we show that representing generic 3-D surfaces as implicit surfaces lets us effectively address these issues.This desirable behavior is completely independent from the way the surface deformations are parame-trized. To show this, we demonstrate our technique in three very different cases: Modeling the deformations of a piece of paper represented by an ordinary triangulated mesh; reconstruction and tracking a person's shoulders whose deformations are expressed in terms of Dirichlet Free Form Deformations; reconstructing the shape of a human face parametrized in terms of a Principal Component Analysis model.

Efficient location area planning for personal communication systems
Authors: Yigal Bejerano, Mark A. Smith, Joseph (Seffi) Naor, Nicole Immorlica
Venue: IEEE/ACM Transactions on Networking (TON) (2006)

A central problem in personal communication systems is to optimize bandwidth usage, while providing Quality of Service (QoS) guarantees to mobile users. Network mobility management, and in particular, location management, consumes a significant portion of bandwidth, which is a necessary overhead for supporting mobile users. We focus our efforts on minimizing this overhead. Unlike previous works, we concentrate on optimizing existing schemes, and so the algorithms we present are easily incorporated into current networks. We present the first polynomial time approximation algorithms for minimum bandwidth location management. In planar graphs, our algorithm provably generates a solution that uses no more than a constant factor more bandwidth than the optimal solution. In general graphs, our algorithm provably generates a solution that uses just a factor O(log n) more bandwidth than optimal where n is the number of base stations in the network. We show that, in practice, our algorithm produces near-optimal results and outperforms other schemes that are described in the literature. For the important case of the line graph, we present a polynomial-time optimal algorithm. Finally, we illustrate that our algorithm can also be used for optimizing the handoff mechanism.

Logistic regression using covariates obtained by product-unit neural network models
Authors: César Hervás-Martínez, Francisco Martínez-Estudillo
Venue: Pattern Recognition (2007)

We propose a logistic regression method based on the hybridation of a linear model and product-unit neural network models for binary classification. In a first step we use an evolutionary algorithm to determine the basic structure of the product-unit model and afterwards we apply logistic regression in the new space of the derived features. This hybrid model has been applied to seven benchmark data sets and a new microbiological problem. The hybrid model outperforms the linear part and the nonlinear part obtaining a good compromise between them and they perform well compared to several other learning classification techniques. We obtain a binary classifier with very promising results in terms of classification accuracy and the complexity of the classifier.

Spline approximation of general volumetric data
Authors: Christian Rössl, Frank Zeilfelder, Günther Nürnberger, Hans-Peter Seidel
Venue: Proceedings of the ninth ACM symposium on Solid modeling and applications (2004)

We present an efficient algorithm for approximating huge general volumetric data sets, i.e. the data is given over arbitrarily shaped volumes and consists of up to millions of samples. The method is based on cubic trivariate splines, i.e. piecewise polynomials of total degree three defined w.r.t, uniform type-6 tetrahedral partitions of the volumetric domain. Similar as in the recent bivariate approximation approaches (cf. [10, 15]), the splines in three variables are automatically determined from the discrete data as a result of a two-step method (see [40]), where local discrete least squares polynomial approximations of varying degrees are extended by using natural conditions, i.e. the continuity and smoothness properties which determine the underlying spline space. The main advantages of this approach with linear algorithmic complexity are as follows: no tetrahedral partition of the volume data is needed, only small linear systems have to be solved, the local variation and distribution of the data is automatically adapted, Bernstein-B&eacute;zier techniques well-known in Computer Aided Geometric Design (CAGD) can be fully exploited, noisy data are automatically smoothed. Our numerical examples with huge data sets for synthetic data as well as some real-world data confirm the efficiency of the methods, show the high quality of the spline approximation, and illustrate that the rendered iso-surfaces inherit a visual smooth appearance from the volume approximating splines.
Uncertainty analysis in political forecasting
Authors: Gleiber Fernandes Royes, Rogério Cid Bastos
Venue: Decision Support Systems (2006)

Medicine, engineering, and finance are traditional fields for the application of Fuzzy Logic (FL); however, in social sciences, the utilization of FL can be intensely explored as a valuable analysis instrument. Joining fuzzy with Multiple Criteria Decision Making (MCDM), the natural complex and uncertain criteria of social problems can be adequately explored. A suitable uncertainty analysis is the focal point in the social field. In this direction, an intelligent computational method for election forecasting is proposed as a practical result of this research. The main objective is to present a more flexible methodology for political assessment comparing to traditional methods.
Projective reconstruction from line-correspondences in multiple uncalibrated images
Authors: A. W. K. Tang, T. P. Ng, Y. S. Hung, C. H. Leung
Venue: Pattern Recognition (2006)

A new approach is proposed for reconstructing 3D lines and cameras from 2D corresponding lines across multiple uncalibrated views. There is no requirement that the 2D corresponding lines on different images represent the same segment of a 3D line, which may not appear on all images. A 3D line is reconstructed by minimizing a geometric cost function that measures the distance of the reprojected end points of the 3D segment from the measured 2D lines on different images. An algorithmic procedure is provided with guaranteed convergence to a solution where the geometric cost function achieves a (local) minimum.
Rediscovering secondary structures as network motifs---an unsupervised learning approach
Authors: Barak Raveh, Ofer Rahat, Ronen Basri, Gideon Schreiber
Venue: Bioinformatics (2007)

Motivation: Secondary structures are key descriptors of a protein fold and its topology. In recent years, they facilitated intensive computational tasks for finding structural homologues, fold prediction and protein design. Their popularity stems from an appealing regularity in patterns of geometry and chemistry. However, the definition of secondary structures is of subjective nature. An unsupervised de-novo discovery of these structures would shed light on their nature, and improve the way we use these structures in algorithms of structural bioinformatics. Methods: We developed a new method for unsupervised partitioning of undirected graphs, based on patterns of small recurring network motifs. Our input was the network of all H-bonds and covalent interactions of protein backbones. This method can be also used for other biological and non-biological networks. Results: In a fully unsupervised manner, and without assuming any explicit prior knowledge, we were able to rediscover the existence of conventional α-helices, parallel β-sheets, anti-parallel sheets and loops, as well as various non-conventional hybrid structures. The relation between connectivity and crystallographic temperature factors establishes the existence of novel secondary structures. Contact:barak.raveh@weizmann.ac.il; gideon.schreiber@weizmann.ac.il

A survey and comparison of CSCW groupware applications
Authors: Jiten Rama, Judith Bishop
Venue: Proceedings of the 2006 annual research conference of the South African institute of computer scientists and information technologists on IT research in developing countries (2006)

Technology plays an ever-increasing role in our everyday lives. We would like it to be a help rather than a hurdle in our work, particularly in collaborating with others. An emerging problem for both individuals and groups is information spread and neglect, where users have the same copy of the same work, stored on various conventional devices, but no way to keep track of where the most recent version resides. One type of computer support collaborative work application, groupware, tackles this problem, aiming to assist in joint authoring projects, where artifacts such as files, pictures, reports and sound are being gathered to form a whole. Such groupware systems - and we survey seven of them - vary in terms of their functional, architectural, focal, temporal, user involvement and platform dependencies. While we found a wide variety of options for each system, there were also strong commonalities. All of them work with closed communities or groups. There is no public file sharing. All users are aware of all other collaborators in the community and all systems focus on collaboration; not sharing. The comparison includes our own system Nomad, a framework for distributed resource management, with special emphasis placed on the accessibility of information stored on detached devices, such as personal computers, laptops, PDA's and flash-disks. In the comparison, Nomad has advantages of flexibility and temporal independence over the other systems, together with low requirements on the user, and a high level of mobility and platform independence. The contributions of this paper are twofold: we identify and define a specific type of CSCW, groupware, together with a set of criteria for evaluating such systems; and we survey and classify some of the main systems according to the criteria, as well as introducing a custom-designed system, Nomad. From these results, a collaborative group of workers can more easily select a specific groupware that suits its needs. Moreover, designers of new systems will find the commonality factors useful, so they can more easily position their own products.
Color Image Segmentation for Objects of Interest with Modified Geodesic Active Contour Method
Authors: Ling Pi, Jinsong Fan, Chaomin Shen
Venue: Journal of Mathematical Imaging and Vision (2007)

In this paper, we propose a novel variational method for color image segmentation using modified geodesic active contour method. Our goal is to detect Object(s) of Interest (OOI) from a given color image, regardless of other objects. The main novelty of our method is that we modify the stopping function in the functional of usual geodesic active contour method so that the new stopping function is coupled by a discrimination function of OOI. By minimizing the functional, the OOI is segmented. Firstly, we study the pixel properties of the OOI by sample pixels visually chosen from OOI. From these sample pixels, by the principal component analysis and interval estimation, the discrimination function of whether a pixel is in the OOI is obtained probabilistically. Then we propose the energy functional for the segmentation of OOI with new stopping function. Unlike usual stopping functions defined by the image gradient, our improved stopping function depends on not only the image gradient but also the discrimination function derived from the color information of OOI. As a result, better than usual active contour methods which detect all objects in the image, our modified active contour method can detect OOI but without unwanted objects. Experiments are conducted in both synthetic and natural images. The result shows that our algorithm is very efficient for detecting OOI even the background is complicated.

Rapid and brief communication: An algorithm for semi-supervised learning in image retrieval
Authors: Ke Lu, Jidong Zhao, Deng Cai
Venue: Pattern Recognition (2006)

We study the problem of image retrieval based on semi-supervised learning. Semi-supervised learning has attracted a lot of attention in recent years. Different from traditional supervised learning. Semi-supervised learning makes use of both labeled and unlabeled data. In image retrieval, collecting labeled examples costs human efforts, while vast amounts of unlabeled data are often readily available and offer some additional information. In this paper, based on support vector machine (SVM), we introduce a semi-supervised learning method for image retrieval. The basic consideration of the method is that, if two data points are close to each, they should share the same label. Therefore, it is reasonable to search a projection with maximal margin and locality preserving property. We compare our method to standard SVM and transductive SVM. Experimental results show efficiency and effectiveness of our method.
