An Implementable Scheme for Universal Lossy Compression of Discrete Markov Sources
Loss of the compressor discrete source coding sequence decoder lossless compression
2015/8/21
We present a new lossy compressor for discrete sources. For coding a source sequence xn, the encoder starts by assigning a certain cost to each reconstruction sequence. It then finds the reconst...

Enhanced Search And Efficient Storage Using Data Compression In Nand Flash Memories
Nand Flash Search data deduplication MISR
2014/12/8
NAND flash memories are popular due to their density and lower cost. However, due to serial access, NAND flash memories have low read and write speeds. As the flash sizes increase to 64GB and beyond, ...
An Algorithm for Image Clustering and Compression
Image segmentation Image compression Fuzzy clustering
2009/7/28
This paper presents a new approach to image compression based on fuzzy clustering. This new approach includes pre-filtering, and fuzzy logic image enhancing to reduce undesirable noise effects on segm...
Compression-Induced Rendering Distortion Analysis for Texture/Depth Rate Allocation in 3D Video Compression
Compression-Induced Rendering Distortion Analysis Texture/Depth Rate Allocation 3D Video Compression
2013/7/16
In 3D video applications, the virtual view is generally rendered by the compressed texture and depth. The texture and depth compression with different bit-rate overheads can lead to different virtual ...
A Novel VLSI Architecture of Hybrid Image Compression Model based on Reversible Blockade Transform
VLSI Discrete Cosine Transform JPEG Hartley transform
2010/2/2
Image compression can improve the performance of
the digital systems by reducing time and cost in image storage
and transmission without significant reduction of the image quality.
Furthermore, the...
B-picture coding in AVS video compression standard
Video coding B-picture Symmetrical mode Direct mode Bi-directional prediction
2013/7/17
This paper first gives a brief overview of the Chinese audio–video coding standard (AVS1) especially on prediction modes of motion compensation for B-picture. Furthermore, two techniques adopted...
FREQUENCY CONTENT ORIENTED MODIFICATION OF QUANTIZATION MATRIX IN DCT – BASED COMPRESSION
Image compression quantization matrix
2010/1/12
In order to improve the compression rate for comparable values of error metrics, we propose a method to modify the standard quantization matrix used in JPEG, according to image frequency content. Unli...
CELLULAR AUTOMATA CODEBOOKS APPLIED TO COMPACT IMAGE COMPRESSION
cellular automata emergent computation image compression
2010/1/12
Emergent computation in semi-totalistic cellular automata (CA) is used to generate a set of basis (or codebook). Such codebooks are convenient for simple and circuit efficient compression schemes base...
