In this paper, a hardware-oriented lossless EEG compression algorithm including a two-stage prediction, voting prediction and tri-entropy coding is proposed. In two stages prediction, 27 conditions and 6 functions are used to decide how to predict the current data from previous data. Then, voting prediction finds optimal function according to 27 conditions for best function to produce best Error (the difference of predicted data and current data). Moreover, a tri-entropy coding technique is developed based on normal distribution. The two-stage Huffman coding and Golomb-Rice coding was used to generate the binary code of Error value. In CHB-MIT Scalp EEG Database, the novel EEG compression algorithm achieves average compression rate to 2.37. The proposed hardware-oriented algorithm is suitable for VLSI implementation due to its low complexity.

IR database compression algorithm using optimized key mask

IR database compression algorithm using optimized key mask

Canadian Conference on Electrical and Computer Engineering (CCECE)

作者： Gurpal Singh Sandeep Kalra B.S. Sohi Department of CSE and IT BBSBEC India Zilog Systems Bangalore India

The rapid growth of Universal Remote Controls, Interactive Remote Controls, electronics Products and Infra-red (IR) Database business has increased the need for effective and standardized IR Database compression techniques. In order to support a large number of Remote control models in a Universal remote, one must compress the available IR database as best as possible. This paper presents a new algorithm for representing optimized key-masks for model command sets. This technique changes the normal key mask into reduced key masks depending on the correlation between the Remote Control keys. In the normal key mask a unique flag represents each remote button/key. In this new technique, all the related buttons/keys can be combined together so that a single flag can represent these set of keys and thus leading to optimized and compressed IR database.

IEEE International Symposium on Geoscience and Remote Sensing (IGARSS)

作者： Md. Al Mamun Xiuping Jia Michael Ryan School of Engineering and Information Technology University of New South Wales Campbell ACT Australia School of Engineering and Information Technology Australian Defence Force Academy Campbell ACT Australia

In this paper, a selective data compression scheme is developed to combine the need for efficient data transmission and the receivers' interest in changes presented in the data by taking the advantage of the fact that receivers hold a copy of previous data. Three-step pre-processing is introduced in this paper. Firstly we separate the unchanged areas (the majority) of the image from the changed areas between successive images of the same area. Secondly, the bands which are sensitive to the changes are identified with the aid of statistical measures. Finally, a binary index image of each band is generated to indicate the two categories. Following this pre-processing, compression of the unchanged areas and changed areas is conducted separately. In this way, different compression algorithms can be applied to each case. As the majority data will be unchanged and only a subset of bands reflects the changes, high compression rate is achievable.

International Symposium on Parallel and Distributed Processing (IPDPS)

作者： Bo Mao Hong Jiang Suzhen Wu Yaodong Yang Zaifa Xi Software School of Xiamen University China Department of Computer Science & Engineering at University of Texas-Arlington USA Computer Science Department of Xiamen University China Microsoft Redmond WA USA

Data compression has become a commodity feature for space efficiency and reliability in flash-based storage systems by reducing write traffic and space capacity demand. However, it introduces noticeable processing overheads on the critical I/O path, which degrades the system performance significantly. Existing data compression schemes for flash-based storage systems use fixed compression algorithms for all the incoming write data, failing to recognize and exploit the significant diversity in compressibility and access patterns of data and missing an opportunity to improve the system performance, the space efficiency or both. To achieve a reasonable trade-off between these two important design objectives, in this paper we introduce an Elastic Data compression scheme, called EDC, which exploits the data compressibility and access intensity characteristics by judiciously matching data of different compressibility with different compression algorithms while leveraging the access idleness. Specifically, for compressible data blocks EDC exploits the compression diversity of the workload, and employs algorithms of higher compression rate in periods of lower system utilization and algorithms of lower compression rate in periods of higher system utilization. For non-compressible (or very lowly compressible) data blocks, it will write them through to the flash storage directly without any compression. The experiments conducted on our lightweight prototype implementation of the EDC system show that EDC saves storage space by up to 38.7%, with an average of 33.7%. In addition, it significantly outperforms the fixed compression schemes in the I/O performance measure by up to 61.4%, with an average of 36.7%.

A novel scheme of orientation and scale mapped RDC (OS-RDC) to improve compression in document images ensuring quality preservation

International Conference on Pattern Recognition

作者： Apurba Das R Remya Imaging Tech Lab. HCL Technologies Ltd. Chennai India

Repeated appearance of any block of spatial data in document images can be cached and encoded single time to get good compression ratio. This Reusable Document Component (RDC) can replicate the blocks of each redundant image at the receiver side at different positions but with same size and orientation. We have proposed a novel algorithm of Orientation Scale mapped RDC (OS-RDC) which can identify and cache repeated image blocks even if they are of different size and orientations. Both the inter-page and intra-page redundancies are addressed ensuring significant quality preservation.

The problem of efficient image compression through neural networks (NNs) is addressed. Some theoretical results on the application of 2-layer linear NNs to this problem are given. Two more elaborate structures, based on a set of NNs, are further presented; they are shown to be very efficient while remaining computationally rather simple.< >

In Internet of Things (IoT), numerous and diverse types of sensors generate a plethora of data that needs to be stored and processed with minimum loss of information. This demands efficient compression mechanisms where loss of information is minimized. Hence data generated by diverse sensors with different signal features require optimum balance between compression gain and information loss. This paper presents a unique analysis of contemporary lossy compression algorithms applied on real field sensor data with different sensor dynamics. The aim of the work is to classify the compression algorithms based on the signal characteristics of sensor data and to map them to different sensor data types to ensure efficient compression. The present work is the stepping stone for a future recommender system to choose the preferred compression techniques for the given type of sensor data.

Midwest Symposium on Circuits and Systems (MWSCAS)

ISBN: (纸本)078037150X

This paper presents a rate control algorithm designed for a 3D wavelet-based video compression scheme, used for real-time video transfer. Wavelet compression schemes demand a rate control algorithm for real-time video communication systems. Furthermore, 3D wavelet compression schemes require, a group of frames (GOF) to process the third dimension of wavelet coefficients. The GOF thus produces an inherent delay in the transmission of real-time video. Also, for real-time video transfer, the frame acquisition rate of the server, and the display frame rate of the client must be equal. These factors must be taken in to consideration when developing a control algorithm to supply a constant frame rate from server to client. Our solution to this rate control problem is comprised of a leaky bucket algorithm used in both the client and server sides.

IEEE Southeastcon

作者： J.D. Lim H.P. Stern Samsung Telecommunications America Inc. Richardson TX USA Department of Electrical and Computer Engineering University of Alabama Tuscaloosa AL USA

This paper proposes a new compression algorithm supporting IPv6 mobility in wireless communications, called the IPv6 header compression algorithm. The idea of the algorithm is to provide an effective compression rate to support the mobility and the spectral efficiency required in wireless networks. The data link layer and the physical layer based on the OSI model are thus considered. To support the mobility it is assumed that any change of other fields in an IPv6 header except care-of-address disconnects the call. The address assignment method and LZW coding delivers significant compression of the long IPv6 header for the initial connection. After the initial communication, the algorithm provides compression through comparator coding and LZW coding. The algorithm's performance is evaluated using both analytic techniques and computer simulation.

Recently, ubiquitous computing has been garnering a great deal of attention. In ubiquitous computing environments, sensor nodes connected to a network are used for collecting sensor data. However, considering the cost needed to set up the network, it may be more convenient to use data loggers that directly send data to users than to use a sensor network. In this paper, we propose a ubiquitous data logger that takes sensor characteristics into consideration in managing data. The logger reduces data volume by selecting an appropriate compression algorithm that takes sensor characteristics into consideration, because the sensor characteristics vary depending on the sensor data.
