我用matlab寫的一個corner detector, 效果比現在流行的harris,susan,CSS等效果要好。
Algorithm is derived from:
X.C. He and N.H.C. Yung, Curvature Scale Space Corner Detector with Adaptive Threshold and Dynamic Region of Support , Proceedings of the 17th International Conference on Pattern Recognition, 2:791-794, August 2004.
Improved algorithm has been included in A Corner Detector based on Global and Local Curvature Properties and submitted to Optical Engineering.
MPEG-2 has 7 distinct parts as well. The first part is the Systems section which defines the container format and the Transport Streams that are designed to carry the digital video and audio over ATSC and DVB. The Program Stream defines the container format for lossy compression on Optical disks, DVDs and SVCDs.

AMANDA, the Advanced Maryland Automatic Network Disk Archiver, is a backup system that allows the administrator to set up a single master backup server to back up multiple hosts over network to tape drives/changers or disks or Optical media. Amanda uses native dump and/or GNU tar facilities and can back up a large number of workstations running multiple versions of Unix. Amanda uses Samba, Cygwin or a native Windows client to back up Microsoft Windows desktops and servers
A new type of cloak is discussed: one that gives all cloaked objects the appearance of a flat conducting
sheet. It has the advantage that none of the parameters of the cloak is singular and can in fact be made
isotropic. It makes broadband cloaking in the Optical frequencies one step closer.
It was proposed that perfect invisibility cloaks can be constructed for hiding objects from electromagnetic
illumination (Pendry et al., Science 312, p. 1780). The cylindrical cloaks experimentally
demonstrated (Schurig et al., Science 314, p. 997) and theoretically proposed (Cai et al., Nat. Photon.
1, p. 224) have however simplified material parameters in order to facilitate easier realization
as well as to avoid infinities in Optical constants. Here we show that the cylindrical cloaks with
simplified material parameters inherently allow the zeroth-order cylindrical wave to pass through
the cloak as if the cloak is made of a homogeneous isotropic medium, and thus visible. To all
high-order cylindrical waves, our numerical simulation suggests that the simplified cloak inherits
some properties of the ideal cloak, but finite scatterings exist.
At present, there is a strong worldwide push toward bringing fiber closer to indi-
vidual homes and businesses. Fiber-to-the-Home/Business (FTTH/B) or close to it
networks are poised to become the next major success story for Optical fiber com-
munications. In fact, FTTH connections are currently experiencing double-digit or
even higher growth rates, e.g., in the United States the annual growth rate was 112%
between September 2006 and September 2007, and their presence can add value of
U.S. $4,000–15,000 to the selling price of a home.
Many times I have been asked to explain “ briefl y ” how SDH, SONET, and the
OTN “ exactly ” work. The questions came mainly from new colleagues, stu-
dents, and users of these technologies, personally or via the usenet newsgroup
comp.dcom.sdh - sonet. I could have referred them to the standards documents,
but to provide a more consistent and clear answer I decided to write this
pocket guide. The objective of this book is that it can be used both as an
introduction as well as a reference guide to these technologies and their spe-
cifi c standards documents.
It is commonly accepted today that Optical fiber communications have revolutionized
telecommunications. Indeed, dramatic changes have been induced in the way we interact
with our relatives, friends, and colleagues: we retrieve information, we entertain and
educate ourselves, we buy and sell, we organize our activities, and so on, in a long list
of activities. Optical fiber systems initially allowed for a significant curb in the cost of
transmission and later on they sparked the process of a major rethinking regarding some,
generation-old, telecommunication concepts like the (OSI)-layer definition, the lack of
cross-layer dependency, the oversegmentation and overfragmentation of telecommunica-
tions networks, and so on.
