Image data compression is concerned with minimization of the number of information
carrying units used to represent an image. Image compression schemes can
be divided into two broad classes: lossless compression schemes and lossy compression
schemes. Lossless compression techniques, as their name implies aim at
exact reconstruction and involve no loss of information. Lossy compression
techniques accept some loss of information, therefore images compressed using a
lossy technique cannot be reconstructed exactly. The distortion in the image
caused by lossy compression may be imperceptible to humans and we obtain much
higher compression ratios than is possible with lossless compression. Lossy
compression scheme can be further divided into three major categories: 1.
Transform coding, 2. Fractal image compression, and 3. Domain Decomposition.
Joint Photographic Expert Group (JPEG), JPEG2000, Binary Tree Triangular
Coding (BTTC) etc. are the examples of lossy image compression methods. This
book describes five new domain decomposition based lossy image compression
algorithms, evaluation of their performance and their parallel implementation. |

Magnetohydrodynamics of Laboratory and Astrophysical Plasmas
With ninety per cent of visible matter in the universe existing in the plasma state, an understanding of magnetohydrodynamics is essential for anyone looking to understand solar and astrophysical processes, from stars to accretion discs and galaxies; as well as laboratory applications focused on harnessing controlled fusion energy. This... | | Windows XP Just the Steps For Dummies
Windows XP is a very robust piece of software with about as much functionality as Einstein on a good day. If you own a Windows XP computer (and I assume you do, or you should rush to the computer store pronto), you spend a lot of time everyday in the Windows XP environment. Knowing how to harness the power of... | | Java I/OBecause it doesn't provide a printf() function like C/C++, some developers think Java isn't up to snuff with files and streams. Author Rusty Harold Elliotte argues against this notion in Java I/O, a book that shows how Java's stream support can help simplify network programming, internationalization, and even compression and... |
