Fast fractal image compression

Fast fractal image compression

引用

international conference on information technology: coding and computing (itcc)

作者： Pou-Yah Wu Department of Mathematics Education National Tainan Teachers College

In this paper, we propose a method of regional search for fractal image compression and decompression. In this method, the search for fractal codes is carried out in a region of the image instead of over the whole image. Because the area surrounding a partitioned block has a high probability of being similar to the block, the use of regional search to find the fractal codes results in sharply reduced compression times and with only minor increases in the compression ratio, as compared to conventional methods. By using a 128/spl times/128 search region, we can compress a 1024/spl times/1024 Lena image on a Pentium II-300 PC in 2.8 seconds, obtaining results of high visual quality, with a compression ratio of 87 and a PSNR of 36.67. By comparison conventional fractal image compression requires 176 seconds, has a compression ratio of 84 and has a PSNR of 39.68. Moreover, if we reduce the search regions to 32/spl times/32 and accept a slightly more basic level of visual quality, the compression time is 1.0 second, the compression ratio is 91 and the PNSR is 33.98.

The problem of data transmission in a heterogeneous network environment involves many considerations, among these: the design and selection of coding schemes and transmissions techniques are the most relevant. The interest in mobile multimedia networks has stimulated the research in this field. Significant progress has been made in this technology. The problem becomes more relevant if we desire to transmit signals in wireline and wireless networks. Progressive transmission is very useful for sending video and, in general, multimedia data over band-limited channels; although it presents problems over noisy channels due to its use of variable length coding. It therefore requires high quality methods to avoid channels noises. One approach is to merge the above mentioned progressive transmission with VQ 2-D-CELP of video over fading channels approach that extends the concept of CELP for speech coding. This technique employ an inverse error predictor filter, an iterative clustering method to design the predictors form an initial array and an algorithm to determine the block size. We state the general design problem, decompose it into simpler subproblems and discuss the solutions to these subproblems.

How many pixels to watermark?

How many pixels to watermark?

international conference on information technology: coding and computing (itcc)

作者： R. Chandramouli N. Memon Department of Electrical and Comp. Engineering Iowa State University Ames USA Department of Comp. and Information Science Polytechnic University Brooklyn USA

Watermark design and detection have been studied as two separate problems so far. However, we show that, if the watermarking algorithm is based on the watermark detection method, then significant gains can be achieved. With a watermark detector based on a sequential hypothesis test rather than a fixed sample size test, the number of watermark pixels can be reduced almost by a factor of two for small detection error probabilities. This is because, the sequential hypothesis test requires less (average) number of pixels to detect the presence/absence of a watermark compared to a fixed sample size detector. The savings in the number of pixels to be watermarked results in an increased immunity to host signal attacks such as cropping. Degradation in the signal quality due to redundant watermarking is also minimized. Further, applications such as DVD require minimal amount of watermarking. The computational efficiency of the proposed watermark detector can also be exploited to efficiently search for watermarks in large image databases.

A simulation for real time data compression

A simulation for real time data compression

international conference on information technology: coding and computing (itcc)

作者： T.L.P. Pham Hanoi University of Technology Vietnam

This paper presents one new basic step in real time data compression. The data under compression are random sequence of variable Y which at time t:y/sub 0/, y/sub 1/, ..., y/sub t/ have occurred. Y-random integer-{0, 1, ..., N-1}. So, at time t, if we produce Y~/sub t+1/ to be really a subset to Y so that y/sub t+1//spl isin/Y~/sub t+1/ then we can write or send the index of y/sub t+1/ in Y~/sub t+1/ instead of y/sub t+1/. To do it we create a function F, which learned from some recent past Y by the fixed rules, to map a known set onto V. The known set is the set known by both sender and receiver, and also, the function F is automatically created the same at both sides.

This paper introduces a graph-oriented model for the conceptual level design of large, complex information systems. This has been shown to be highly effective to the system designer from the perspectives of maintainability and upgradability. Basically due to the flat structure and the lack of holding multidimensional data, the relational model does not provide a structural approach to the system designer. The alternative object oriented model offers the structured approach but also is not able to describe various intermodular relationships spread over the same or different levels within a data model. The graph data model allows dynamic regrouping of related entities at the designers' level. We have proposed an appropriate data structure and the corresponding DDL has been developed. Test runs on a simulated environment further establish its computational efficiency.

A hard real-time tasks model for the VBR video server

A hard real-time tasks model for the VBR video server

引用

international conference on information technology: coding and computing (itcc)

作者： Jae-Dong Lee Department of Computer Science and Engineering Kyungnam University

At the design of the video server to service video data as real-time, we must consider network bandwidth, buffer space and disk bandwidth. As buffer space and disk bandwidth affect each other tightly, they should be considered at the same time. In this paper, we propose the hard real-time tasks' model for the streams on the video server. The stream on the server can be considered as the hard real-time task in that the server must guarantee the continuity of streams like the hard real-time system must guarantee the deadline of tasks. The management of streams in the server is induced from the scheduling of real-time tasks. We propose hard read-time tasks models for the video server and the scheduling algorithms for real-time tasks. The real-time scheduling algorithms are used for admission control of streams, scheduling of disks, and management of buffers in the video server. We design the effective video server using the real-time tasks a model. We evaluate the performance of our suggested video server via simulation. We show that our mechanism can service more streams with a few buffers simultaneously.

Transparent and robust audio data hiding in subband domain

Transparent and robust audio data hiding in subband domain

international conference on information technology: coding and computing (itcc)

作者： Xin Li H.H. Yu Department of Electrical Engineering Princeton University Princeton NJ USA Panasonic Information and Networking Technologies Laboratory Panasonic Technologies Inc. Princeton NJ USA

Data hiding embeds extra information into digital media for the purpose of authentication, annotation and copyright protection. Transparency and robustness are two contradictory requirements for any data hiding scheme. This paper studies audio data hiding using the spread spectrum (SS) technique in the subband domain. On the transparency part, we propose a novel method of tuning psycho-acoustic models employed in audio compression to control the audibility of the introduced distortion for data hiding. On robustness part, we have studied the feature selection and synchronization problem in order to maximize the survivability of the embedded data. Our study shows that mid-band coefficients are appropriate features for data embedding. We propose to track/recover synchronization of the audio signal before the detection, facilitating the extraction of the embedded data. Experiment results have shown that our data hiding scheme in the subband domain can survive a wide range of attacks while providing transparent audio quality and abundant embedding capacity (>20 bps).

Improvements in telecommunication and computer technologies have made integrated services packet-switched networks possible. It is expected that a significant portion of future networks will carry prerecorded video and that traffic in applications such as video on demand (VoD) will include high-fidelity audio, short multimedia clips, and full-length movies. In this paper we study the effect of video rate smoothing, of prerecorded VBR sources, on network utilization and admission control of a VoD system, such that the end users receive a satisfactory service. The enhancement piecewise constant rate transmission and transport (e-PCRTT) algorithm is used as the smoothing algorithm, which utilizes equal size intervals. The effect of smoothing on the statistical characteristics of multiplexed video streams is explored. We found that synchronization between the smoothing intervals can significantly improve the efficiency of the smoothing process by reducing the number of bandwidth changes and the rate variability of the multiplexed stream. In this paper we propose an admission control policy in which a bandwidth rate-plan is negotiated at stream initiation. The algorithm is evaluated via simulation for the VoD scenario.

Recent advances in computer technologies have made it feasible to provide multimedia services. As a result, the research and development of continuous media servers has received more attention in recent years. In general, these servers consist of multiple zone-bit recording (ZBR) disks or multiple storage nodes connected through the high-speed network to construct a distributed server. One key issue in developing continuous media servers is the allocation of data into ZBR disks. We propose a novel data placement scheme, called VARBT (variable block-size and data-transfer-time), to fully utilize the characteristics of ZBR disks. The proposed scheme determines data block size in each zone completely according to the capacity of that zone thus the storage utilization is 100%. During the process of data retrieval, the data transfer rate for each block is equal to the bandwidth of each physical zone thus the bandwidth utilization is also maximal. This scheme can be applied not only to a single-disk platform, but also to a multiple-disk server and even a distributed server with multiple storage nodes. Through simulations and performance evaluation, we found that VARBT scheme has the smaller average block size, required memory space and system response time to support more simultaneous streams, and meanwhile it achieves 100% storage utilization and bandwidth utilization.

The growing number of applications for 3D graphics and imaging systems in the mass market requires the customized approach to the design of high-performance 3D graphics and imaging system architectures. That fact coupled with the strong trends to industrial standardization of graphics API, such as OpenGL, leads to enhanced portability for imaging and graphics applications. The progress on the hardware support of API functionality gives a real possibility to use a top-down approach in the design of custom graphics/imaging systems based on the mixed hardware/software implementation of the OpenGL architecture. Software simulation is a relatively cheap and fast way for initial graphics architecture template development and evaluation to acquire the structure and parameters that can be used later for HDL elaboration and simulation. This paper discusses a 3D graphics and imaging system architecture model implementation based on OpenGL API hardware support simulation. The object-oriented approach has been used for this development of analytic and software models simulating hardware units on different stages of the graphics pipeline. The Interactive Imaging System Architecture Composer has been developed in this project for fast run-time simulation management, data acquisition and interpretation. The expandable set of architecture templates uses a reconfigurable shared library of "virtual hardware units" simulating the different hardware structures for graphics and image processing.
