An MCMC Approach to Lossy compression of Continuous Sources

An MCMC Approach to Lossy Compression of Continuous Sources

引用

Data compression Conference (DCC)

作者： Dror Baron Tsachy Weissman Electrical Engineering Department Technion-Israel Institute of Technology Haifa Israel Department of Electrical Engineering University of Stanford Stanford CA USA

ISBN: (纸本)9781424464258

Motivated by the Markov chain Monte Carlo (MCMC) relaxation method of Jalali and Weissman, we propose a lossy compression algorithm for continuous amplitude sources that relies on a finite reproduction alphabet that grows with the input length. Our algorithm asymptotically achieves the optimum rate distortion (RD) function universally for stationary ergodic continuous amplitude sources. However, the large alphabet slows down the convergence to the RD function, and is thus an impediment in practice. We thus propose an MCMC-based algorithm that uses a (smaller) adaptive reproduction alphabet. In addition to computational advantages, the reduced alphabet accelerates convergence to the RD function, and is thus more suitable in practice.

In data compression or source coding algorithms, input sequences of symbols are converted to shorter sequences while the original information remains unchanged. One of the well-known data compression algorithms is Deflate which is designed based on the LZ method. Deflate method has three different modes where its second mode is applicable for real-time applications. In this mode, a certain static table of Huffman codes is employed during the coding procedure. In this paper, a new version of deflate algorithm is proposed and implemented in hardware. In the proposed method, a new basic coding table is employed. This table is modified adaptively based on the input sequence. Simulation results show that in this adaptive algorithm, the coding performance is improved. In the hardware implementation of the new method, through some parallelism concepts, we try to improve the hardware utilization and throughput.

Medical imaging is crucial for early detection and diagnosis of illnesses. The increasing amount of high resolution scans being done every day requires efficient compression algorithms. A magnetic resonance image (MRI) consists of a series of many cuts or slices. Viewed as a 3D image, it contains a 3D figure surrounded by background. This background is not clinically relevant.

International Conference on Computer and Automation Engineering, ICCAE

作者： Farhad Keissarian University of Wollongong UAE

ISBN: (纸本)9781424455690

In this paper, a new variable block-size image compression scheme is presented. A quadtree segmentation is employed to generate blocks of variable size according to their visual activity. Inactive blocks are coded by the block mean, while active blocks are coded by the proposed matching algorithm using a set of parameters associated with the pattern appearing inside the block. Both the segmentation and the pattern matching are carried out through histogram analysis of block residuals. The use of pattern parameters at the receiver together with the quadtree code reduces the cost of reconstruction significantly and exploits the efficiency of the proposed technique.

International Conference on Electronics And Information Engineering (ICEIE)

作者： YiKun Zhang Xiao Li DengXin Hua Hao Chen HaiYan Jin Xi'an University of Technology Xi'an China

Lidar raw echo data has characteristics such as huge data quantity, strong discreteness and unpredictability. According to the construction of Lidar monitoring network of atmospheric environment, the existing network can not provide enough bandwidth to transmit Lidar data in real time. In this paper, we propose a novel hybrid lossless compression algorithm to reduce the transmission amount, namely the probability statistics lossless compression algorithm base on the improved LZW(Lempel-Ziv-Welch), which combines Huffman coding. With experiment on the raw two-value atmospheric data, we verify the effectiveness of our approach that the compression ratio is close to 9.5:1 and the coding efficiency is up to 98%.

On power and performance tradeoff of L2 cache compression

On power and performance tradeoff of L2 cache compression

引用

Norchip

作者： Chandrika Jena Tim Mason Tom Chen Department of ECE Colorado State University Fort Collins CO USA

This paper presents the power-performance trade off of three different cache compression algorithms. Cache compression improves performance, since the compressed data increases the effective cache capacity by reducing the cache misses. The unused memory cells can be put into sleep mode to save static power. The increased performance and saved power due to cache compression must be more than the delay and power consumption added due to CODEC(COmpressor and DECompressor) block respectively. Among the studied algorithms, power-delay characteristic of Frequent Pattern compression(FPC) is found to be the most suitable for cache compression.

Analytical Motion Blur Rasterization with compression 10

Analytical Motion Blur Rasterization with Compression

Conference on High-performance Graphics

作者： Carl Johan Gribel Michael Doggett Tomas Akenine-Moller Lund University Lund University Intel Corporation

ISBN: (纸本)9781617827242

We present a rasterizer, based on time-dependent edge equations, that computes analytical visibility in order to render accurate motion blur. The theory for doing the computations in a rasterization framework is derived in detail, and then implemented. To keep the frame buffer requirements low, we also present a new oracle-based compression algorithm for the time intervals. Our results are promising in that high quality motion blurred scenes can be rendered using a rasterizer with rather low memory requirements. Our resulting images contain motion blur for both opaque and transparent objects.

This paper presents a theory of lossless digital compression. Quality of voice signal is not important for voice communication. In hearing music high quality music is always recommended. For this emphasis is given on the quality of speech signal. To save more music it is needed to save them consuming smaller memory space. In proposed compression 8-bit PCM/PCM speech signal is compressed. When values of samples are varying they are kept same. When they are not varying the number of samples containing same value is saved. After compression the signal is also an 8-bit PCM/PCM. MPEG-4 ALS is applied in this compressed PCM signal for better compression.
