A few short years ago, the applications for
video were somewhat confined—analog was
used for broadcast and cable television, VCRs,
set-top boxes, televisions and camcorders.
Since then, there has been a tremendous and
rapid conversion to digital video, mostly based
on the MPEG-2 video compression standard.
Today, in addition to the legacy DV,
MPEG-1 and MPEG-2 audio and video com-
pression standards, there are three new high-
performance video compression standards.
These new video codecs offer much higher
video compression for a given level of video
quality.

After the successful global introduction during the past decade of the second generation (2G) digital
mobile communications systems, it seems that the third generation (3G) Universal Mobile Communication
System (UMTS) has finally taken off, at least in some regions. The plethora of new services that
are expected to be offered by this system requires the development of new paradigms in the way scarce
radio resources should be managed. The Quality of Service (QoS) concept, which introduces in a natural
way the service differentiation and the possibility of adapting the resource consumption to the specific
service requirements, will open the door for the provision of advanced wireless services to the mass
market.

密碼學(xué)界牛人Victor Shoup用C++編寫(xiě)數(shù)論類(lèi)庫(kù)。
NTL is a high-performance, portable C++ library providing data structures and algorithms for arbitrary length integers for vectors, matrices, and polynomials over the integers and over finite fields and for arbitrary precision floating point arithmetic.
NTL provides high quality implementations of state-of-the-art algorithms for:
* arbitrary length integer arithmetic and arbitrary precision floating point arithmetic
* polynomial arithmetic over the integers and finite fields including basic arithmetic, polynomial factorization, irreducibility testing, computation of minimal polynomials, traces, norms, and more
* lattice basis reduction, including very robust and fast implementations of Schnorr-Euchner, block Korkin-Zolotarev reduction, and the new Schnorr-Horner pruning heuristic for block Korkin-Zolotarev
* basic linear algebra over the integers, finite fields, and arbitrary precision floating point numbers.

To review what a metaball is, and how to render them and to describe a
new optimization I ve made for rendering metaballs. For complex scenes,
it can render hundreds of times faster, though I m certain others have
discovered this trick as well. It does very slightly change the
characteristic shape of the blobs, but there is no loss in image quality
whatsoever. (I actually developed all this about two years ago, but just
now felt like writing it all down, and had the time!)

This project features a complete JPEG Hardware Compressor (standard Baseline DCT, JFIF header) with 2:1:1 subsampling, able to compress at a rate of up to 24 images per second (on XC2V1000-4 @ 40 MHz with resolution 352x288).
Image resolution is not limited. It takes an RGB input (row-wise) and outputs to a memory the compressed JPEG image. Its quality is comparable to software solutions.

In the last decade the processing of polygonal meshes has
emerged as an active and very productive research area. This
can basically be attributed to two developments:
Modern geometry acquisition devices, like laser scanners
and MRT, easily produce raw polygonal meshes of
ever growing complexity
Downstream applications like analysis tools (medical
imaging), computer aided manufacturing, or numerical
simulations all require high quality polygonal meshes
as input.
The need to bridge the gap between raw triangle soup data
and high-quality polygon meshes has driven the research on
ecient data structures and algorithms that directly operate
on polygonal meshes rather than on a (most often not
feasible) intermediate CAD representation.
