Some notes on reconstruction algorithms and “choosing the right parameter”

Posted on May 4, 2011 by mt4

First, somewhat unrelated, here are some Acrobat Reader shortcuts.  I’m especially excited about Alt + <– and Alt + –> to go backward or forward a “view”.  So for example, in a paper with internal hyperlinks to the citations as … Continue reading →

Circulant Matrices, Gabor Frames, Weyl-Heisenberg groups, and the Fourier Transformm

Posted on March 2, 2011 by mt4

In signal processing the marks of great physicist-mathematicians of the early 20th century and beyond are everywhere.  Apparently when Gabor authored his seminal paper (cited by 4087 according to google scholar), he was building on the foundations of laid by … Continue reading →
