From: nargess on 8 Apr 2010 14:34 Hi, I am interested in implementing the 2D capon method, similar to what has been done for the 1D case here: http://www.dsprelated.com/showmessage/78531/1.php Any suggestions as what is the best way to modify the above code to make it work for 2d signals? I am looking at the following paper, and am interested in applying capon similarly: http://www.emo.org.tr/ekler/23d0a5671efd29e_ek.pdf However, their code seems different from what was posted here on DSPRelated. I appreciate your help and comments, Nargess

You shouldn't look at the code, but rather at the expressions. The key is to realize how the 1D Capon works, and how to generalize that methodology to 2D. The 2nd equation 20 of the last paper seems to be a reasonable 2D generalization of the first equation 20, which is the 1D version of Capon's method. (But do work trough the arithmetics to see if the result is correct. The inconsistent equation numbering is a hint that the authors of the paper might not pay as acute attention to details as one might have whished for.) Apart from that, doce similarity means nothing. There are several possible algorithms for each step, and several possible implemenations of each algorithm, not to mention that coding style an attentiuon to detail is a highly personal trait. Don't expect to find very advanced, working code in usenet fora. Rune

A "2D capon" would have been quite an expensive capon in its day... maybe during a meat shortage, or war rationing you could get that much. A 2D capon, to justify its price, would have been LARGE but not tender.... that size bird is 10 years old! Cheers Steve |
