HDR Image Compression by Local Adaptation for Scene and Display Using Retinal Model
Authors: Lijie Wang, Takahiko Horiuchi, Hiroaki Kotera
Venue: IEICE - Transactions on Information and Systems (2007)

Adaptation process of retina helps human visual system to see a high dynamic range scene in real world. This paper presents a simple static local adaptation method for high dynamic range image compression based on a retinal model. The proposed simple model aims at recreating the same sensations between the real scene and the range compressed image on display device when viewed after reaching steady state local adaptation respectively. Our new model takes the display adaptation into account in relation to the scene adaptation based on the retinal model. In computing local adaptation, the use of nonlinear edge preserving bilateral filter presents a better tonal rendition in preserving the local contrast and details while avoiding banding artifacts normally seen in local methods. Finally, we demonstrate the effectiveness of the proposed model by estimating the color difference between the recreated image and the target visual image obtained by trial and error method.

An information-theoretic approach to automatic evaluation of summaries
Authors: Chin-Yew Lin, Guihong Cao, Jianfeng Gao, Jian-Yun Nie
Venue: Proceedings of the main conference on Human Language Technology Conference of the North American Chapter of the Association of Computational Linguistics (2006)

Until recently there are no common, convenient, and repeatable evaluation methods that could be easily applied to support fast turn-around development of automatic text summarization systems. In this paper, we introduce an information-theoretic approach to automatic evaluation of summaries based on the Jensen-Shannon divergence of distributions between an automatic summary and a set of reference summaries. Several variants of the approach are also considered and compared. The results indicate that JS divergence-based evaluation method achieves comparable performance with the common automatic evaluation method ROUGE in single documents summarization task; while achieves better performance than ROUGE in multiple document summarization task.
USim: A User Behavior Simulation Framework for Training and Testing IDSes in GUI Based Systems
Authors: A. Garg, S. Vidyaraman, S. Upadhyaya, K. Kwiat
Venue: Proceedings of the 39th annual Symposium on Simulation (2006)

Anomaly detection systems largely depend on user profile data to be able to detect deviations from normal activity. Most of this profile data is currently based on command-line instructions/directives executed by users on a system. With the advent and extensive usage of graphical user interfaces (GUIs), command-line data can no longer fully represent user's complete behavior which is essential for effectively detecting the anomalies in these GUI based systems. Collection of user behavior data is a slow and time consuming process. In this paper, we present a new approach to automate the generation of user data by parameterizing user behavior in terms of user intention (malicious/normal), user skill level, set of applications installed on a machine, mouse movement and keyboard activity. The user behavior parameters are used to generate templates, which can be further customized. The framework is called USim which can achieve rapid generation of user behavior data based on these templates for GUI based systems. The data thus generated can be utilized for rapidly training and testing intrusion detection systems (IDSes) and improving their detection precision
Data Organization and Data Comparison for Model Validation in Faster-than-Real-Time Simulation
Authors: Dimosthenis Anagnostopoulos, Mara Nikolaidou
Venue: Proceedings of the 39th annual Symposium on Simulation (2006)

Validation is an essential feature of faster-than-real-simulation (FRTS), since models must be validated prior used for nearfuture predictions. As no relevant approaches exist in the literature, the paper contribution is to propose an approach a) accomplishing validation as a real-time, automated process, with low time overhead, b) dealing with the complexity of validation data, as the number and type of the data compared may be changing and c) realizing the transition from validation process conceptual design to an efficient real-time execution. A formal data organization scheme (data model) and algorithms for constructing and accessing it are implemented for this purpose. Realization of model validation in a FRTS experiment on a single-queue/multi-server processing system is presented to exhibit the applicability of the proposed approach. The proposed organization scheme may also be applied in simulation studies where timing and automation requirements are not critical.
A practical FPGA-based framework for novel CMP research
Authors: Sewook Wee, Jared Casper, Njuguna Njoroge, Yuriy Tesylar, Daxia Ge, Christos Kozyrakis, Kunle Olukotun
Venue: Proceedings of the 2007 ACM/SIGDA 15th international symposium on Field programmable gate arrays (2007)

Chip-multiprocessors are quickly gaining momentum in all segments of computing. However, the practical success of CMPs strongly depends on addressing the difficulty of multithreaded application development. To address this challenge, it is necessary to co-develop new CMP architecture with novel programming models. Currently, architecture research relies on software simulators which are too slow to facilitate interesting experiments with CMP software without using small datasets or significantly reducing the level of detail in the simulated models. An alternative to simulation is to exploit the rich capabilities of modern FPGAs to create FPGA-based platforms for novel CMP research. This paper presents ATLAS, the first prototype for CMPs with hardware support for Transactional Memory (TM), a technology aiming to simplify parallel programming. ATLAS uses the BEE2 multi-FPGA board to provide a system with 8 PowerPC cores that run at 100MHz and runs Linux. ATLAS provides significant benefits for CMP research such as 100x performance improvement over a software simulator and good visibility that helps with software tuning and architectural improvements. In addition to presenting and evaluating ATLAS, we share our observations about building a FPGA-based framework for CMP research. Specifically, we address issues such as overall performance, challenges of mapping ASIC-style CMP RTL on to FPGAs, software support, the selection criteria for the base processor, and the challenges of using pre-designed IP libraries.
Application Development for Cics Web Services
Venue:  (2006)

This IBM Redbook focuses on developing Web service applications in CICS. It takes the broad view of developing and modernizing CICS applications for XML, Web services, SOAP, and SOA support, and lays out a reference architecture for developing these kinds of applications. We start by discussing Web services in general, then review how CICS implements Web services. We offer an overview of different development approaches: bottom-up, top-down, and meet-in-the-middle. After laying out the foundations, we review the CICS catalog manager sample application, as this is the application we used as a basis. We then look at how you would go about exposing a CICS application (namely, the catalog manager sample application) as a Web service provider, again looking at the different approaches. The book then steps through the process of creating a CICS Web service requester. We close out by looking at CICS application aggregation (including 3270 applications) with WebSphere Developer for zSeries Service Flow Modeler (SFM). The final chapter offers hints and tips that should help you when implementing this technology. The ACM Portal is published by the Association for Computing Machinery. Copyright © 2010 ACM, Inc.

FPGA-friendly code compression for horizontal microcoded custom IPs
Authors: Bita Gorjiara, Daniel Gajski
Venue: Proceedings of the 2007 ACM/SIGDA 15th international symposium on Field programmable gate arrays (2007)

Shrinking time-to-market and high demand for productivity has driven traditional hardware designers to use design methodologies that start from high-level languages. However, meeting timing constraints of automatically generated IPs is often a challenging and time-consuming task that must be repeated every time the specification is modified. To address this issue, a new generation of IP-design technologies that is capable of generating custom datapaths as well as programming an existing one is developed. These technologies are often based on Horizontal Microcoded Architectures. Large code size is a well-know problem in HMAs, and is referred to as "code bloating" problem.In this paper, we study the code size of one of the new HMA-based technologies called NISC. We show that NISC code size can be several times larger than a typical RISC processor, and we propose several low-overhead dictionary-based code compression techniques to reduce the code size. Our compression algorithm leverages the knowledge of "don't care" values in the control words to better compress the content of dictionary memories. Our experiments show that by selecting proper memory architectures the code size of NISC can be reduced by 70% (i.e. 3.3 times) at cost of only 9% performance degradation. We also show that some code compression techniques may increase number of utilized block RAMs in FPGA-based implementations. To address this issue, we propose combining dictionaries and implementing them using embedded dual-port memories.
Voltage Island Generation in Cell Based Dual-Vdd Design
Authors: Yici Cai, Bin Liu, Qiang Zhou, Xianlong Hong
Venue: IEICE Transactions on Fundamentals of Electronics, Communications and Computer Sciences (2007)

The voltage island style has been widely accepted as an effective way to design low power high performance chips. This paper proposes an automated voltage island generation flow in standard cell based designs. Two important objectives in voltage island designs are addressed in this flow: 1) reducing power dissipation under given performance constraints; 2) reducing implementation overheads, mainly layout overheads caused by cell clustering to form islands. The first objective is handled with timing and power driven netweighting and timing analysis in voltage assignment. For the second objective, we propose layout aware voltage assignment, i.e., voltage assignment during placement. We iteratively perform the following to adjustments: adjustment on voltage assignment to facilitate voltage island generation, and adjustment on cell locations to cluster cells in voltage islands. These iterations lead to a flow featured with tightly integrated voltage assignment and cell placement. Experimental results have demonstrated the advantages of our approach.
Fast arbitrary splitting of deforming objects
Authors: Denis Steinemann, Miguel A. Otaduy, Markus Gross
Venue: Proceedings of the 2006 ACM SIGGRAPH/Eurographics symposium on Computer animation (2006)

We present a novel algorithm for efficiently splitting deformable solids along arbitrary piecewise linear crack surfaces in cutting and fracture simulations. We propose the use of a meshless discretization of the deformation field, and a novel visibility graph for fast update of shape functions in meshless discretizations. We decompose the splitting operation into a first step where we synthesize crack surfaces as triangle meshes, and a second step where we use the newly synthesized surfaces to update the visibility graph, and thus the meshless discretization of the deformation field. The separation of the splitting operation into two steps, along with our novel visibility graph, enables high flexibility and control over the splitting trajectories, provides fast dynamic update of the meshless discretization, and facilitates an easy implementation, making our algorithm scalable, versatile, and suitable for a large range of applications, from computer animation to interactive medical simulation.

Post-route LUT output polarity selection for timing optimization
Authors: Kai Zhu
Venue: Proceedings of the 2007 ACM/SIGDA 15th international symposium on Field programmable gate arrays (2007)

Modern FPGA architectures support flexible polarity propagation in the fabric of logic blocks and interconnects. For example, the output of a lookup-table (LUT) logic block can be inverted by inverting all the bits in the LUT table. The rise and fall delays in either a LUT or a routing multiplexer usually differ substantially. The flexibility of polarity propagation and the difference between the rise and fall delays provide an opportunity to further optimize timing. This paper describes an algorithm to minimize the longest path delay by adjusting LUT output polarity after routing. The algorithm can be extended to reduce active leakage power in routing multiplexers while meeting timing constraints. The algorithm is efficient,easy to implement, and does not require change in placement and routing. Preliminary experiments show that the algorithm can reduce the longest path delay by up to 5.8% and on average 2.5% on a set of customer designs.
Image Authentication Scheme for Resisting JPEG, JPEG2000 Compression and Scaling
Authors: Chih-Hung Lin, Wen-Shyong Hsieh
Venue: IEICE - Transactions on Information and Systems (2007)

This paper presents a secure and simple content-based digital signature method for verifying the image authentication under JPEG, JPEG2000 compression and scaling based on a novel concept named lowest authenticable difference (LAD). The whole method, which is extended from the crypto-based digital signature scheme, mainly consists of statistical analysis and signature generation/verification. The invariant features, which are generated from the relationship among image blocks in the spatial domain, are coded and signed by the sender's private key to create a digital signature for each image, regardless of the image size. The main contributions of the proposed scheme are: (1) only the spatial domain is adopted during feature generation and verification, making domain transformation process unnecessary; (2) more non-malicious manipulated images (JPEG, JPEG2000 compressed and scaled images) than related studies can be authenticated by LAD, achieving a good trade-off of image authentication between fragile and robust under practical image processing; (3) non-malicious manipulation is clearly defined to meet closely the requirements of storing images or sending them over the Internet. The related analysis and discussion are presented. The experimental results indicate that the proposed method is feasible and effective.
