IEEE International Workshop on Electronic Design, Test and Applications (DELTA)

This paper presents a hybrid image compression scheme based on a block based compression algorithm referred to as Vector Quantization (VQ) combined with the Differential Pulse Code Modulation (DPCM) technique. The proposed image compression technique called the PVQ scheme results in enhanced image quality as compared to the standalone VQ. The generated codebooks for the PVQ scheme are more robust for image coding than that of the VQ. This made our system a suitable candidate for developing on chip image sensor with integrated data compression processor. The proposed system was validated through FPGA implementation. The resulting implementation achieved good compression and image quality with moderate system complexity.

DNA compression using referential compression algorithm

DNA compression using referential compression algorithm

International Conference on Contemporary Computing (IC3)

作者： Kanika Mehta Satya Prakash Ghrera Department of Computer Science and Engineering Jaypee University Of Information Technology Waknaghat Himachal Pradesh

With rapid technological development and growth of sequencing data, an umpteen gamut of biological data has been generated. As an alternative, Data compression is employed to reduce the size of data. In this direction, this paper proposes a new reference-based compression approach, which is employed as a solution. Firstly, a reference has been constructed from the common sub strings of randomly selected input sequences. Reference set is a pair of key and value, where key is a fingerprint (or a unique id) and value is a sequence of characters. Next, these given sequences are compressed using referential compression algorithm. This is attained by matching the input with the reference and hence, replacing the match found in input by its fingerprints contained in the reference, thereby achieving better compression. The experimental results of this paper show that the approach proposed herein, outperforms the existing approaches and methodologies applied so far.

Image compression is one of the most widely used groups of signal processing schemes in real-time applications. There are various algorithms for compressing images, each with pros and cons. Each method of data compression behaves differently for various types of data, thus a review of the common image algorithms seems necessary to compare the compression ratio, compression and decompression time, and generated file sizes. This paper aims to provide an insight into the characteristics of commonly used image-compression algorithms. Each algorithm is tested with controlled test images to determine the operational capabilities of each algorithm for different test cases. Subsequently, the performance of each algorithm is simulated and compared with other methods. Discussions on how algorithms behave with various test images are given in detail. The desired outcome of this study is a clear description of compression algorithms, and determining the suitability of each algorithm for different applications.

NASA/ESA Conference on Adaptive Hardware and Systems

In this paper, we present an FPGA implementation of a novel adaptive and predictive algorithm for lossy hyperspectral image compression. This algorithm was specifically designed for on-board compression, where FPGAs are the most attractive and popular option, featuring low power and high-performance. However, the traditional RTL design flow is rather time-consuming. High-level synthesis (HLS) tools, like the well-known CatapultC, can help to shorten these times. Utilizing CatapultC, we obtain an FPGA implementation of the lossy compression algorithm directly from a source code written in C language with a double motivation: demonstrating how well the lossy compression algorithm would perform on an FPGA in terms of throughput and area;and at the same time showing how HLS is applied, in terms of source code preparation and CatapultC settings, to obtain an efficient hardware implementation in a relatively short time. The P&R on a Virtex 5 5VFX130 displays effective performance terms of area (maximum device utilization at 14%) and frequency (80 MHz). A comparison with a previous FPGA implementation of a lossless to near-lossless algorithm is also provided. Results on a Virtex 4 4VLX200 show less memory requirements and higher frequency for the LCE algorithm.

IEEE Workshop on Advances in Techniques for Analysis of Remotely Sensed Data

We propose compression algorithms for hyperspectral images with enhanced discriminant features. As the dimension of remotely sensed images increases, the need for efficient compression algorithms for hyperspectral images also increases. However, when hyperspectral images are compressed with conventional image compression algorithms, which have been developed to minimize mean squared errors, discriminant features of the original data may be lost during the compression process. In this paper, we propose to apply preprocessing prior to compression in order to preserve such discriminant information. In particular, we enhance discriminant features before a compression algorithm is applied. Experiments show that the proposed method provides improved classification accuracies than the existing compression algorithms.

Data compression Conference (DCC)

作者： Mayumi Kato Chia-Tien Dan Lo Department of Computer Science University of Technology San Antonio USA

Only summary form *** has been introduced to the mobile/wireless handsets and Java enabled handsets are now prevalent in the market, showing their successful launch. A variety of attractive services have been developed and promise a lot of fun to our daily lives, which are however targeted to the high end products that are very expensive. We focus on economic types with similar performance to the high end products. Memory compression is a key technique to achieve the goal and is integrated into a Java runtime environment. We save memory with runtime compression and reduce power by a memory bank partitioning technique (powering off unused memory banks). In memory compression algorithms and the Java runtime environment are studied. The Wilson and Kaplan (WK) algorithm is discussed as in-memory compression and introduced to the Java heap as an alternative of the garbage collection (gc). Experiments show around 10% of speedup and up to 45% of memory saving in the application core part (20.0 % of memory overhead for a user interface). The Java system using the memory compression outperforms its base configuration and will give further chance to reduce memory demand in combination with the garbage collection designed for the Java compressed heap. Experiments show that the in-heap memory compression technique can save more than 50 % (up to 60 %) of the heap demand and that half of the memory banks for the Java heap may never be turned on. 50 % of the power consumption (memory leakage current) can be saved. The hardware compressor and decompressor are currently ten thousand times faster than the software counterparts. The time overhead could be negligible by introducing the hardware compressor and decompressor. Hardware/software codesign is an additional key to achieve our goal. The contribution of the runtime memory and heap compression is threefold: small memory demand, lower power consumption, and negligible time overhead in battery-powered handsets. Future work i

Lossless image compression is the technique now that allows to keep the quality high as long as the file size is being minimized to meet the needs of uploading or archiving [1]. The other category consists of Deflate whose shortcomings are fast speed and lower efficiency [2]. By considering this, smaller files size might never be the case but it is the best alternative for quality images and this forms part of formats like PNG and ZIP [3]. On the other hand, the BROTLI admirably shines with its extremely high compression ratios, when dealing with repeated pattern of information [4]. On the contrast, it pertains to the extremely resource intensive, which may eventually need more computing power, as the ratio is in favor of the compression [5]. Regardless of the chosen technique, the outcome remains consistent: for a compressed file whose data original size has been truncated, having a size that ranges from pixels to a file which can work on them without giving a distorted image, targeting those who need high-end images but small file sizes [6].

IEEE Workshop on Multimedia Signal Processing

作者： Jae-Young Sim Chang-Su Kim J.C.-C. Kuo Sang-Uk Lee Signal Processing Laboratory School of Electrical Engineering Seoul National University South Korea Integrated Media Systems Center and Department of Electrical Engineering University of Southern California USA

An efficient progressive compression and interactive transmission algorithm for 3D normal meshes, based on rate-distortion optimization, are proposed in this work. A normal mesh is partitioned into several segments, which are encoded independently. By truncating the bitstream for each segment optimally using a distortion model, the proposed algorithm yields a higher coding gain than the conventional approach. Moreover, to support interactive transmission of 3D models from client's viewpoint, each segment can be endowed with different priority of transmission. The view-dependent processing technique enables to reduce the transmission bandwidth considerably while maintaining the same visual quality.
