Data compression Conference (DCC)
作者: Suzanne J. Matthews Seung-Jin Sul Tiffani L. Williams Department of Computer Science & Engineering Texas A and M University USA
The primary advantage of TreeZip is its use of semantic compression, which allows us to uniquely store tree relationship information. Phylogenetic trees are stored in a format known as a Newick representation, which u... 详细信息

Midwest Symposium on Circuits and Systems (MWSCAS)
作者: Ruth M. Aguilar-Ponce J. Luis Tecpanecatl-Xihuitl Alfonso Alba-Cadena Edga Arce-Santana School of Science Autonomous University of San Luis Potosí San Luis Potosi Mexico
A motion estimation algorithm based on Phase-Only Correlation (POC) function is proposed. Motion estimation is one of the key tasks in several applications such as video encoding. Motion estimation is the process of f... 详细信息

IEEE International Symposium on Information Theory
作者: Barlas Oǧuz Venkat Anantharam Department of Electrical Engineering and Computer Sciences University of California Berkeley Berkeley CA USA
Analysis of variable bit-rate video data has shown that long range dependence persists across a wide variety of codecs. While codecs are generally lossy, one may conjecture, as a partial explanation for this fact, tha... 详细信息

IEEE Asia Pacific Conference on Circuits and Systems
作者: Chandrika Jena Tim Mason Tom Chen Dept. of ECE Colorado State University
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... 详细信息

35th Conference on Current Trends in Theory and Practice of Computer Science
作者: Mayordomo, Elvira Moser, Philippe Univ Zaragoza Dept Informat & Ingn Sistemas Maria de Luna 1 Zaragoza 50018 Spain Natl Univ Ireland Maynooth Dept Comp Sci Maynooth Kildare Ireland
This paper considers online compression algorithms that use at most polylogarithmic space (plogon). These algorithms correspond to compressors in the data stream model. We study the performance attained by these algor... 详细信息
