An Adaptive Tone Mapping Algorithm for High Dynamic Range Images
Authors: Jian Zhang, Sei-Ichro Kamata
Venue: Computational Color Imaging: Second International Workshop, CCIW 2009, Saint-Etienne, France, March 26-27, 2009. Revised Selected Papers (2009)

Real world scenes contain a large range of light intensities which range from dim starlight to bright sunlight. A common task of tone mapping algorithms is to reproduce high dynamic range(HDR) images on low dynamic range(LDR) display devices such as printers and monitors. In this paper, a new tone mapping algorithm is proposed for the display of HDR images. Inspired by the adaptive process of the human visual system, the proposed algorithm utilized the center-surround Retinex processing. The novelty of our method is that the local details are enhanced according to a non-linear adaptive spatial filter (Gaussian filter), whose shape is adapted to high-contrast edges of the image. The proposed method uses an adaptive surround instead of the traditional pre-defined circular. Therefore, the algorithm can preserve visibility and contrast impression of high dynamic range scenes in the common display devices. The proposed method is tested on a variety of HDR images, and we also compare it to previous work. The results show good performance of our method in terms of visual quality.
Vi-xfst: a visual regular expression development environment for Xerox finite state tool
Authors: Kemal Oflazer, Yasin Yilmaz
Venue: Proceedings of the 7th Meeting of the ACL Special Interest Group in Computational Phonology: Current Themes in Computational Phonology and Morphology (2004)

This paper describes Vi-xfst, a visual interface and a development environment, for developing finite state language processing applications using the Xerox Finite State Tool, xfst. Vi-xfst lets a user construct complex regular expressions via a drag-and-drop visual interface, treating simpler regular expressions as "Lego Blocks". It also enables the visualization of the structure of the regular expression components, providing a bird's eye view of the overall system, enabling a user to easily understand and track the structural and functional relationships among the components involved. Since the structure of a large regular expression (built in terms of other regular expressions) is now transparent, users can also interact with regular expressions at any level of detail, easily navigating among them for testing. Vi-xfst also keeps track of dependencies among the regular expressions at a very fine-grained level. So when a certain regular expression is modified as a result of testing, only the dependent regular expressions are recompiled resulting in an improvement in development process time, by avoiding file level recompiles which usually causes redundant regular expression compilations.
Non-monotonic Reasoning Supporting Wireless Sensor Networks for Intelligent Monitoring: The SINDI System
Authors: Alessandra Mileo, Davide Merico, Roberto Bisiani
Venue: Proceedings of the 10th International Conference on Logic Programming and Nonmonotonic Reasoning (2009)

In recent years there has been growing interest in solutions for the delivery of clinical care for the elderly, due to the large increase in aging population. Monitoring a patient in his home environment is necessary to ensure continuity of care in home settings, but this activity must not be too invasive and a burden for clinicians. We prototyped a system called SINDI (Secure and INDependent lIving), focused on i) collecting data about the person and the environment through Wireless Sensor Networks (WSN), and ii) reasoning about these data both to contextualize them and to support clinicians in understanding patients' well being as well as in predicting possible evolutions of their health.
Interactive Photo Viewing on Ubiquitous Displays
Authors: Han-Sol Ryu, Yeo-Jin Yoon, Seon-Min Rhee, Soo-Mi Choi
Venue: Proceedings of the 5th International on ConferenceUniversal Access in Human-Computer Interaction. Part II: Intelligent and Ubiquitous Interaction Environments (2009)

This paper presents a method of showing photos interactively based on a user's movements using multiple displays. Each display can identify the user and measure how far away he is using an RFID reader and ultrasonic sensors. When he approaches to within a certain distance from the display, it shows a photo that resides in his photo album and provides quasi-3D navigation using the TIP (tour into the picture) method. In addition, he can manipulate photos directly using a touch-screen or remotely using an air mouse. Moreover, a group of photos can be represented as a 3D cube and can be transferred to PDA for a continuous viewing on other displays.

Authors: George Sobral Silveira, Alisson Vasconcelos Brito, Elmar U. K. Melcher
Venue: Proceedings of the 22nd Annual Symposium on Integrated Circuits and System Design: Chip on the Dunes (2009)

With the growth of number of transistors, thermal density and market drive towards battery power, the necessity to develop low power integrated circuits is evident. There are several methodologies and techniques that help in the development of this type of SoC. There is consensus that the techniques when applied in the initial phases of the design flow, especially in design and architecture of the system have a higher impact factor in relation to those applied during the implementation or layout phase. Considering this fact, the possibility to accomplish functional verification of the system with low power design modeled in TLM and RTL is attractive. The purpose of this paper is to show a method for functional verification of power gate design in RTL. A case study is presented to demonstrate the application of power gate using new features for the OSCI SystemC simulator developed for this purpose and the accomplishment of the functional verification of the design using the VeriSC methodology.

Faster and Timing-Attack Resistant AES-GCM
Authors: Emilia Käsper, Peter Schwabe
Venue: Proceedings of the 11th International Workshop on Cryptographic Hardware and Embedded Systems (2009)

We present a bitsliced implementation of AES encryption in counter mode for 64-bit Intel processors. Running at 7.59 cycles/byte on a Core 2, it is up to 25% faster than previous implementations, while simultaneously offering protection against timing attacks. In particular, it is the only cache-timing-attack resistant implementation offering competitive speeds for stream as well as for packet encryption: for 576-byte packets, we improve performance over previous bitsliced implementations by more than a factor of 2. We also report more than 30% improved speeds for lookup-table based Galois/Counter mode authentication, achieving 10.68 cycles/byte for authenticated encryption. Furthermore, we present the first constant-time implementation of AES-GCM that has a reasonable speed of 21.99 cycles/byte, thus offering a full suite of timing-analysis resistant software for authenticated encryption.

The Conformal Monogenic Signal of Image Sequences
Authors: Lennart Wietzke, Gerald Sommer, Oliver Fleischmann, Christian Schmaltz
Venue: Statistical and Geometrical Approaches to Visual Motion Analysis: International Dagstuhl Seminar, Dagstuhl Castle, Germany, July 13-18, 2008. Revised Papers (2009)

Based on the research results of the Kiel University Cognitive Systems Group in the field of multidimensional signal processing and Computer Vision, this book chapter presents new ideas in 2D/3D and multidimensional signal theory. The novel approach, called the conformal monogenic signal, is a rotationally invariant quadrature filter for extracting i(ntrinsic)1D and i2D local features of any curved 2D signal - such as lines, edges, corners and circles - without the use of any heuristics or steering techniques. The conformal monogenic signal contains the monogenic signal as a special case for i1D signals - such as lines and edges - and combines monogenic scale space, local energy, direction/orientation, both i1D and i2D phase and curvature in one unified algebraic framework. The conformal monogenic signal will be theoretically illustrated and motivated in detail by the relation of the 3D Radon transform and the generalized Hilbert transform on the sphere. The main idea of the conformal monogenic signal is to lift up 2D signals by stereographic projection to a higher dimensional conformal space where the local signal features can be analyzed with more degrees of freedom compared to the flat two-dimensional space of the original signal domain. The philosophy of the conformal monogenic signal is based on the idea to make use of the direct relation of the original two-dimensional signal and abstract geometric entities such as lines, circles, planes and spheres. Furthermore, the conformal monogenic signal can not only be extended to 3D signals (image sequences) but also to signals of any dimension.The main advantages of the conformal monogenic signal in practical applications are the completeness with respect to the intrinsic dimension of the signal, the rotational invariance, the low computational time complexity, the easy implementation into existing Computer Vision software packages and the numerical robustness of calculating exact local curvature of signals without the need of any derivatives.

Authors: Scott Axelrod
Venue: Proceedings of the ANLP-NAACL 2000 Workshop on Conversational Systems (2000)

The IBM flight information system is a speech based conversational system which allows users to create multi-leg airline travel itineraries based on live flight availability information. We discuss here the components of the system relating to natural language generation. The deep generation component of the system decides what to say based on information shared with the user about constraints on flights. The surface generation component generates text based on a simple error catching mechanism and a few basic "generation constructs".

Cultivated Land Change and Its Human Driving Forces Based on RS and GIS in Fuzhou, China
Authors: Dewen Wu, Jinchuan Huang, Xiaolei Zhang, Hanying Mao
Venue: Proceedings of the 2009 International Conference on Environmental Science and Information Application Technology - Volume 01 (2009)

This paper analyzed the characteristics and major human driving forces of cultivated land change in Fuzhou, China, using remote sensing (RS) images, geographic information system (GIS) spatial analysis, and socio-economic data. Based on the RS images and GIS spatial analysis, a change matrix was constructed to detect land-use change from 1989 to 2005. The result indicated that paddy fields and dry land decreased enormously. The vast loss of cultivated land in this period mainly was presented in two aspects. On the one hand, cultivated land was largely occupied by construction land. On the other hand, cultivated land was converted internally into other agricultural land-use types for relatively high economic gains. In addition, regression analysis method was used to identify critical factors from human factors related to the change of cultivated land in Fuzhou. The result indicated that population growth, economic development, and benefit driving for rural households were closely related to the rapid decrease of cultivated land in Fuzhou. However, the result of regression analysis also revealed that the increasingly strict land policies of the central government of China failed to play a very positive role in protecting cultivated land and controlling the rapid expansion of urban construction land in Fuzhou. Finally, the paper analyzed the reasons behind the ineffective execution of land policies and proposed next research priorities in protecting cultivated land and controlling the rapid expansion of urban construction land.

Authors: Xiao-fei Zhang, Shou-yi Li, Yao-long Chen, Jun-rui Chai
Venue: Advances in Engineering Software (2009)

Based on the construction property of rolled compacted concrete dam cast layer by layer, three-dimensional finite element relocating mesh method was developed in the paper to simulate construction process and compute temperature field. The computation model of relocating mesh method is expatiated in detail. The feasibility and error of the relocating mesh method were analyzed and demonstrated. The computation results were verified with the temperature observation data of an RCC arch dam. The results show that the method has high calculation precision, less computer run time and less memory. The values computed with the method are in the same trend with the observation data. The method has proved to be effective in simulating construction process and computing temperature field of RCC dam.

In a preliminary evaluation the added flexibility for browsing and searching was highly appreciated and we received valuable suggestions for future research.
A mediated publish-subscribe system for inter-institutional process support in healthcare
Authors: Christoph P. Neumann, Florian Rampp, Richard Lenz, Michael Daum
Venue: Proceedings of the Third ACM International Conference on Distributed Event-Based Systems (2009)

Inadequate availability of patient information is a major cause for medical errors and affects costs in healthcare. Traditional information integration in healthcare does not solve the problem. For chronic diseases and multimorbidity, the significance of patient information availability is yet increasing. Applying a document-oriented paradigm to a mediated publish-subscribe infrastructure allows to foster inter-institutional information exchange in healthcare. The goal of the proposed architecture is to provide information exchange between strict autonomous healthcare institutions, bridging the gap between primary and secondary care, following traditional paper-based working practice. In a distributed healthcare scenario, the patient has to maintain sovereignty over any personal health information. Therefore, the proposed mediated publish-subscribe architecture essentially decouples the roles of information author and information publisher into distinct actors.

Authors: Swapnil Shrivastava, Supriya N. Pal
Venue: Proceedings of the 2009 International Conference on Advances in Social Network Analysis and Mining (2009)

In the scientific and commercial domains, graph as a data structure has become increasingly important for modeling sophisticated structures especially the interactions within them. Mining the knowledge from graph data has become a major research topic in recent data mining studies. Researchers have designed several efficient algorithms for mining various substructures (subgraphs) within the graph. Several graph visualization tools and techniques exist. But there is a need to define a unified framework for finding and visualizing substructures from graph. In this paper we propose a graph mining framework that captures entities and relations between entities from different data sources. The framework further models this data as a graph and facilitates the dense substructure extraction and frequent substructure discovery in order to find substructures. It also supports knowledge visualization using graphs.

Authors: Hongwei Cui
Venue: Proceedings of the 2009 International Conference on Measuring Technology and Mechatronics Automation - Volume 01 (2009)

This paper presents an approach to control air fuel ratio of a Liquefied Petroleum Gas (LPG) automotive engine. The optimization of compression ratio is also described in this paper. HC, CO & NOx emissions of LPG engines can be reduced after the application of air fuel ratio control. The control strategy presented in this paper is proved to be appropriate. H∞ control method is used in this engine system because of the robust advantages. The control precision of air fuel ratio is distinctly improved. The software and hardware designs of control system are also described in this paper. H∞ air fuel ratio control and the performance optimization have been developed on a 1.46-liter 4-cylinde spark-ignition LPG engine. The experimental results show that this system can achieve satisfactory control effect. This helps LPG automotive engine to have desirable power output and fuel consumption.
Granularity as a Cognitive Factor in the Effectiveness of Business Process Model Reuse
Authors: Oliver Holschke, Jannis Rake, Olga Levina
Venue: Proceedings of the 7th International Conference on Business Process Management (2009)

Reusing design models is an attractive approach in business process modeling as modeling efficiency and quality of design outcomes may be significantly improved. However, reusing conceptual models is not a cost-free effort, but has to be carefully designed. While factors such as psychological anchoring and task-adequacy in reuse-based modeling tasks have been investigated, information granularity as a cognitive concept has not been at the center of empirical research yet. We hypothesize that business process granularity as a factor in design tasks under reuse has a significant impact on the effectiveness of resulting business process models. We test our hypothesis in a comparative study employing high and low granularities. The reusable processes provided were taken from widely accessible reference models for the telecommunication industry (enhanced Telecom Operations Map). First experimental results show that Recall in tasks involving coarser granularity is lower than in cases of finer granularity. These findings suggest that decision makers in business process management should be considerate with regard to the implementation of reuse mechanisms of different granularities. We realize that due to our small sample size results are not statistically significant, but this preliminary run shows that it is ready for running on a larger scale.
