The ultimate goal of such systems is to achieve image quality comparable to that currently achieved with flatbed scanners even for curved, warped, or curled pages. This can be achieved by high-accuracy 3D modeling of the page surface, followed by a "flattening" of the surface. A number of previous systems have either assumed only perspective distortions, or used techniques like structured lighting, shading, or side-imaging for obtaining 3D shape. This paper describes a system for handheld camera-based document capture using general purpose stereo vision methods followed by a new document dewarping technique. Examples of shape modeling and dewarping of book images is shown.","lang":"eng"}],"month":"01","main_file_link":[{"open_access":"0","url":"http://pub.ist.ac.at/~chl/papers/ulges-doceng2004.pdf"}],"publisher":"ACM","quality_controlled":0},{"extern":1,"citation":{"chicago":"Oliver, Dominik, Cheng Lien, Malle Soom, Thomas Baukrowitz, Peter M Jonas, and Bernd Fakler. “Functional Conversion between A-Type and Delayed Rectifier K+ Channels by Membrane Lipids.” Science.

We study the complexity of finding such Nash equilibria, and show that the payoff of some epsilon-Nash equilibrium in memoryless strategies can be epsilon-approximated in NP. We study the important subclass of n-player turn-based probabilistic games, where at each state at most one player has a nontrivial choice of moves. For turn-based probabilistic games, we show the existence of epsilon-Nash equilibria in pure strategies for games where the objective of player i is a Borel set B-i of infinite traces.

In contrast to classical game theory, we consider lexicographic objectives: first, each player tries to maximize her own payoff, and then, the player tries to minimize the opponent's payoff. Such objectives arise naturally in the verification of systems with multiple components. There, instead of proving that each component satisfies its specification no matter how the other components behave, it often suffices to prove that each component satisfies its specification provided that the other components satisfy their specifications. We say that a Nash equilibrium is secure if it is an equilibrium with respect to the lexicographic objectives of both players. We prove that in graph games with Borel objectives, which include the games that arise in verification, there may be several Nash equilibria, but there is always a unique maximal payoff profile of secure equilibria. We show how this equilibrium can be computed in the case of omega-regular objectives, and we characterize the memory requirements of strategies that achieve the equilibrium.","lang":"eng"}],"month":"08","publisher":"IEEE","quality_controlled":0,"day":"09","year":"2004","publication_status":"published","date_published":"2004-08-09T00:00:00Z","doi":"10.1109/LICS.2004.1319610","date_created":"2018-12-11T12:05:45Z","page":"160 - 169"},{"citation":{"chicago":"Zhang, Hui, Stephan Baader, Michael K Sixt, Joachim Kappler, and Uwe Rauch. “Neurocan-GFP Fusion Protein: A New Approach to Detect Hyaluronan on Tissue Sections and Living Cells.” Journal of Histochemistry and Cytochemistry.

In Drosophila, the Dpp morphogen forms a long-range concentration gradient by spreading from a restricted source in the developing wing. It has been assumed that Dpp spreads by extracellular diffusion. Under this assumption, the main role of endocytosis in gradient formation is to downregulate receptors at the cell surface. These surface receptors bind to the ligand and thereby interfere with its long-range movement. Recent experiments indicate that Dpp spreading is mediated by Dynamin-dependent endocytosis in the target tissue, suggesting that extracellular diffusion alone cannot account for Dpp dispersal. Here, we perform a theoretical study of a model for morphogen spreading based on extracellular diffusion, which takes into account receptor binding and trafficking. We compare profiles of ligand and surface receptors obtained in this model with experimental data. To this end, we monitored directly the pool of surface receptors and extracellular Dpp with specific antibodies. We conclude that current models considering pure extracellular diffusion cannot explain the observed role of endocytosis during Dpp long-range movement."}],"intvolume":" 131","month":"01","publisher":"Company of Biologists","publication":"Development","language":[{"iso":"eng"}],"day":"01","publication_status":"published","year":"2004","date_created":"2018-12-11T12:07:41Z","issue":"19","doi":"10.1242/dev.01335","volume":131,"date_published":"2004-01-01T00:00:00Z","page":"4843 - 4856","_id":"4224","status":"public","type":"journal_article","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","extern":"1","date_updated":"2021-01-12T07:55:26Z","citation":{"ista":"Kruse K, Pantazis P, Bollenbach MT, Julicher F, Gonzalez Gaitan M. 2004.

In essence this is the joint generating function for a coalescent and the random background in which it evolves. We use this to characterize, for the diffusion approximation, the probability of identity in state at the neutral locus of a sample of two individuals (whose type at the selected locus is known) as solutions to a system of ordinary differential equations. The only subtlety is to find the boundary conditions for this system. Finally, numerical examples are presented that illustrate the accuracy and predictions of the diffusion approximation. In particular, a comparison is made between this approach and one in which the frequencies at the selected locus are estimated by their value in the absence of fluctuations and a classical structured coalescent model is used."}],"date_created":"2018-12-11T12:07:52Z","issue":"2","volume":14,"date_published":"2004-05-01T00:00:00Z","page":"754 - 785","publication":"Annals of Applied Probability","day":"01","year":"2004","publication_status":"published","status":"public","type":"journal_article","_id":"4253","title":"Coalescence in a Random Background","author":[{"full_name":"Nicholas Barton","orcid":"0000-0002-8548-5240","last_name":"Barton","first_name":"Nicholas H","id":"4880FE40-F248-11E8-B48F-1D18A9856A87"},{"full_name":"Etheridge, Alison M","last_name":"Etheridge","first_name":"Alison"},{"first_name":"Anja","full_name":"Sturm, Anja K","last_name":"Sturm"}],"publist_id":"1842","extern":1,"date_updated":"2021-01-12T07:55:38Z","citation":{"mla":"Barton, Nicholas H., et al. “Coalescence in a Random Background.” Annals of Applied Probability, vol. 14, no. 2, Institute of Mathematical Statistics, 2004, pp. 754–85.","short":"N.H.

As neurons project towards their targets they require target-derived signals to establish mature axonal projections and acquire neuronal traits such as the expression of distinct combinations of neurotransmitters.

In this paper, we give a characterization of the energy functions that can be minimized by graph cuts. Our results are restricted to functions of binary variables. However, our work generalizes many previous constructions and is easily applicable to vision problems that involve large numbers of labels, such as stereo, motion, image restoration, and scene reconstruction. We give a precise characterization of what energy functions can be minimized using graph cuts, among the energy functions that can be written as a sum of terms containing three or fewer binary variables. We also provide a general-purpose construction to minimize such an energy function. Finally, we give a necessary condition for any energy function of binary variables to be minimized by graph cuts.

This article reports a general implementation of the SMV approach using a multiprocessor scheduling algorithm. Each motion state is regarded as a processor and each volume is regarded as a job. An efficient scheduling that completes all jobs in minimal time is maintained even when the motion pattern changes. Initial experiments demonstrated that SMV significantly increased the scan efficiency of navigatorgated MRI.","lang":"eng"}],"author":[{"full_name":"Vladimir Kolmogorov","last_name":"Kolmogorov","first_name":"Vladimir","id":"3D50B0BA-F248-11E8-B48F-1D18A9856A87"},{"full_name":"Nguyen, Thành D","last_name":"Nguyen","first_name":"Thành"},{"first_name":"Anthony","last_name":"Nuval","full_name":"Nuval, Anthony"},{"first_name":"Pascal","full_name":"Spincemaille, Pascal","last_name":"Spincemaille"},{"first_name":"Martin","last_name":"Prince","full_name":"Prince, Martin R"},{"first_name":"Ramin","full_name":"Zabih, Ramin","last_name":"Zabih"},{"first_name":"Yusu","last_name":"Wang","full_name":"Wang, Yusu"}],"publist_id":"3508","title":"Multiprocessor scheduling implementation of the simultaneous multiple volume SMV navigator method","date_updated":"2021-01-12T07:41:34Z","citation":{"ista":"Kolmogorov V, Nguyen T, Nuval A, Spincemaille P, Prince M, Zabih R, Wang Y. 2004.

The feature space is then clustered, and each pixel is labeled with the cluster that contains its feature vector. A major limitation of this approach is that feature space clusters generally lack spatial coherence (i.e., they do not correspond to a compact grouping of pixels). In this paper, we propose a segmentation algorithm that operates simultaneously in feature space and in image space. We define an energy function over both a set of clusters and a labeling of pixels with clusters. In our framework, a pixel is labeled with a single cluster (rather than, for example, a distribution over clusters). Our energy function penalizes clusters that are a poor fit to the data in feature space, and also penalizes clusters whose pixels lack spatial coherence. The energy function can be efficiently minimized using graph cuts. Our algorithm can incorporate both parametric and non-parametric clustering methods. It can be applied to many optimization-based clustering methods, including k-means and k-medians, and can handle models which are very close in feature space. Preliminary results are presented on segmenting real and synthetic images, using both parametric and non-parametric clustering."}],"intvolume":" 2","month":"06","publisher":"IEEE","quality_controlled":0},{"extern":1,"citation":{"ista":"Rother C, Kolmogorov V, Blake A. 2004.

Classical image segmentation tools use either texture (colour) information, e.g. Magic Wand, or edge (contrast) information, e.g. Intelligent Scissors. Recently, an approach based on optimization by graph-cut has been developed which successfully combines both types of information. In this paper we extend the graph-cut approach in three respects. First, we have developed a more powerful, iterative version of the optimisation. Secondly, the power of the iterative algorithm is used to simplify substantially the user interaction needed for a given quality of result. Thirdly, a robust algorithm for "border matting" has been developed to estimate simultaneously the alpha-matte around an object boundary and the colours of foreground pixels. We show that for moderately difficult examples the proposed method outperforms competitive tools."}],"intvolume":" 23","month":"08","main_file_link":[{"url":"http://research.microsoft.com/pubs/67890/siggraph04-grabcut.pdf","open_access":"0"}],"quality_controlled":0,"publisher":"ACM"},{"title":"Controlled unfolding and refolding of a single sodium/proton antiporter using atomic force microscopy","author":[{"full_name":"Kedrov, Alexej","last_name":"Kedrov","first_name":"Alexej"},{"first_name":"Christine","full_name":"Ziegler, Christine","last_name":"Ziegler"},{"last_name":"Janovjak","full_name":"Harald Janovjak","orcid":"0000-0002-8023-9315","first_name":"Harald L","id":"33BA6C30-F248-11E8-B48F-1D18A9856A87"},{"full_name":"Kühlbrandt, Werner","last_name":"Kühlbrandt","first_name":"Werner"},{"first_name":"Daniel","full_name":"Mueller, Daniel J","last_name":"Mueller"}],"publist_id":"2981","extern":1,"date_updated":"2021-01-12T07:43:21Z","citation":{"apa":"Kedrov, A., Ziegler, C., Janovjak, H.

Although transmembrane α-helices and extracellular polypeptide loops exhibited sufficient stability to individually establish potential barriers against unfolding, two helices predominantly unfolded pairwise, thereby acting as one structural unit. Many of the potential barriers were detected unfolding NhaA either from the C-terminal or the N-terminal end. It was found that some molecular interactions stabilizing secondary structural elements were directional, while others were not. Additionally, some interactions appeared to occur between the secondary structural elements. After unfolding ten of the 12 helices, the extracted polypeptide was allowed to refold back into the membrane. After five seconds, the refolded polypeptide established all secondary structure elements of the native protein. One helical pair showed a characteristic spring like “snap in” into its folded conformation, while the refolding process of other helices was not detected in particular. Additionally, individual helices required characteristic periods of time to fold. Correlating these results with the primary structure of NhaA allowed us to obtain the first insights into how potential barriers establish and determine the folding kinetics of the secondary structure elements.","lang":"eng"}]},{"extern":1,"citation":{"ista":"Janovjak HL, Struckmeier J, Hubain M, Kessler M, Kedrov A, Mueller D. 2004.

Here, single bacteriorhodopsin molecules were mechanically unfolded from native purple membranes using atomic force microscopy and force spectroscopy. The energy landscape of individual transmembrane α helices and polypeptide loops was mapped by monitoring the pulling speed dependence of the unfolding forces and applying Monte Carlo simulations. Single helices formed independently stable units stabilized by a single potential barrier. Mechanical unfolding of the helices was triggered by 3.9–7.7 Å extension, while natural unfolding rates were of the order of 10−3 s−1. Besides acting as individually stable units, helices associated pairwise, establishing a collective potential barrier. The unfolding pathways of individual proteins reflect distinct pulling speed-dependent unfolding routes in their energy landscapes. These observations support the two-stage model of membrane protein folding in which α helices insert into the membrane as stable units and then assemble into the functional protein.","lang":"eng"}],"intvolume":" 12","month":"05","publisher":"Cell Press","quality_controlled":0},{"extern":1,"citation":{"ista":"Edelsbrunner H, Harer J. 2004.Jacobi sets of multiple Morse functions.
