TÀI LIỆU VỀ DATA COMPRESSION BOOK

PKZIP is a relatively inexpensive program that offers both superior compression ratios and
compression speed. At this writing, the current shareware version is PKZip V2.04g and can be found on many bulletin boards and online forums. Katz’s company, PKWare, also sells a commercial v[r]

Bitplane . Each pixel in a digital image is represented by several bits. The set of all the
k th bits of all the pixels in the image is the k th bitplane of the image. A bi-level image, for example, consists of one bitplane. (See also Bi-level Image.)
Bitrate . In general, the term “bitrate” ref[r]

The important feature of the DCT, which makes it so useful in data compression, is that it takes correlated input data and concentrates its energy in just the first few transform coefficients. If the input data consists of correlated quantities, then most of the n transfor[r]

7.3 SCSU: Unicode Compression 259
The method described in this section is due to [Wolf et al. 00]. It is a standard compression scheme for Unicode, abbreviated SCSU. It compresses strings of code points. Like any compression method, it works by removing redundancy from the o[r]

1.9. The straightforward answer is that the decoder doesn’t know but it does not need to know. The decoder simply reads tokens and uses each offset to locate a string of text without having to know whether the string was a first or a last match.

Direct shear test is used to find the shear strength parameters of soil quickly. In direct shear test, only the stresses at failure are known, whereas in the triaxial test, the complete state of stress is assumed to be known at all stages during the test. Therefore, triaxial test is the most conf[r]

Finally, we would both like to thank you, our readers, the current and next generation of business analysts, information architects, systems designers, data modelers, DBAs and applica- tion developers. You are the ones who will introduce these methods of temporal data management to you[r]

Predictive encoding
In predictive encoding, the differences between samples are encoded instead of encoding all the sampled values. This type of compression is normally used for speech. Several standards have been defined such as GSM (13 kbps), G.729 (8 kbps), a[r]

The third factor that affects the storage and transmission of data is security. Gener- ally, we do not want our data transmissions to be intercepted, copied, and read on their way. Even data saved on a disk may be sensitive and should be hidden from prying eyes. This is why digit[r]

MPEG-4 Visual and H.264 have related but significantly different visions. Both are con- cerned with compression of visual data but MPEG-4 Visual emphasises flexibility whilst H.264’s emphasis is on efficiency and reliability. MPEG-4 Visual provides a highly flexible toolkit of coding techn[r]

JPEG: The Most Common Internet Format
The main advantage of the JPEG format is that it provides you with the ability to eliminate image information to reduce file size. This process is called compression.
The advantage here is that smaller files transfer more quickly over the Internet. U[r]
