The sequence consists of 128 samples, the first 118 of which are 0, followed by a sharp increase in value. The 128-point DCT of this sequence is shown in Figure 16.8. Notice that many of these ...

Intel IPP provides optimized implementations of the common data compression algorithms, including the BZIP2*, ZLIB*, LZO*, and a new LZ4* function, as “drop-in” replacements for the original ...

We have already discussed a simple method of lossy data compression, coarser sampling and/or quantization (CS&Q in Table 27-1). This involves reducing the number of bits per sample or entirely discard ...

Microsoft is open-sourcing its cloud-compression algorithm and optimized hardware implementation for cloud storage. Microsoft is contributing that algorithm, known as "Project Zipline," plus the ...

Google is open-sourcing a new general purpose data compression library called Zopfli that can be used to speed up Web downloads. The Zopfli Compression Algorithm, which got its name from a Swiss ...

Alireza Doostan is leading a major effort for real-time data compression for supercomputer research.. A professor in the Ann and H.J. Smead Department of Aerospace Engineering Sciences at the ...
