I am using R for environmental forensics (determination of the sources and/or groupings in mixtures of organic chemicals in the field). The goal is to determine in there are groups of samples with similar/dissimilar compositions, and to assign samples to a potential source or a mixture of sources based on the composition (unmixing and source allocation). Typically there are 10 to 50 chemicals that

Dear R-ians, I want to perform an linear unmixing of image pixels in fractions of pure endmembers. Therefore I need to perform a constrained linear least-squares problem that looks like : min || Cx - d || ? where sum(x) = 1. I have a 3x3 matrix C, containing the values for endmembers and I have a 3x1 column vector d (for every pixel in the image). In theory my x values should all be in the

I am curious whether anybody has or is developing this capability within R. I have not found any software yet that has this capability and I am not sure whether it is too new a method and nobody is actually using it, or if there are other means to get the same analysis that I do not know of. Any information regarding developments or use of this method would be helpful. Melanie Edwards

Hi, I am currently encoding 32 Khz/Qual-10/UWB encode mode, with MANUAL_ALLOC enabled ( similar to the c5x/c6x configuration). In file sb_celp.c, I noticed the scratch memory grow during recursive (UWB -> WB) calls to 'sb_encode'. 1. 'stack' was not tracked (with 'tmp_stack' as done at other palaces) after/before - auto-correlation/Levinson-Durbin scope (~line

Hi everyone, I have got some questions about Speex, I am sorry if my questions are too newbie: 1. For the LP analysis, did Speex use the AR (Autoregressive) model or the ARMA model? 2. Am I right to say that Speex use a multistage VQ (since I believe Speex employs two or more VQ consecutively - based on the manual it says that Speex uses dynamically selectable codebooks (linear

Wondering if anyone here has ever tried installing this https://github.com/bootchk/resynthesizer as a gimp plugin in Centos-7, with gimp 2.8.16?? I find the installation instructions (for the binary tarball) are minimal and whatever I do, it doesn't seem to appear in the gimp menus, as it should. I've used an older version (0.14) from years ago in older versions of gimp, but how does

WinXP, R-2.9.1 LS., I have been trying to solve a (for me) tricky issue. No matter what I've tried, I just can't find a way to do this. This is the issue: I have a text file (ansi text) "titles.txt" with lines of text; here is an example of such a file: >>>>> a brief history of polio vaccines anti-vaccination movements and their interpretations early warning

I have a brand new installation of Rocky Linux 9.1 (I know, this isn't a Rocky mailing list, but I can't find anything on this on Rocky forums, etc. so I figured I would ask here), and I installed Gimp, and would like to install the Resynthesizer plugin package. Trying to compile it from source, autogen.sh complains that I don't have the gimp development libraries installed. In fact,

I dunno. I guess it could be. Went to the Gimp site and saw that glib-devel was mentioned there. My tired old brain is a bit confused by this, since most other -devel packages put -devel following the program/package name, and gimp doesn't. I'll give that a try, though, to see if it takes care of my issue. Thanks! On Tue, Mar 21, 2023 at 2:32?AM Simon Matter <simon.matter at

that's what I thought at first, but there is no gimp-devel either installed, or available.

Hello, I apologize that this is off-topic. I am seeking information on perception of graphical data, in an effort to improve the plots I produce. Would anyone point me to literature reviews in this area? (Or keywords to try on google?) Is this located somewhere near cognitive science, psychology, human factors research? For example, some specific questions I have are: I recall as a child

I've been working on improving packet loss concealment in my VoIP client -- I hadn't actually realized speex performed some PLC until I was looking at nb_decode(). There are two things I'd like to do, and I think both will require some modification to nb_decode() and nb_decode_lost(). - I'd like to have my frames overlap by some number of samples. This is intended to reduce the

Hi, Jean-Marc Valin wrote: > Not sure I understand your question. Change the order of what within what? In cb_search, we iterate nb_subvect times over a codebook, finding nb_subvect codebook entries to quantize the excitation signal. After finding these nb_subvect codebook entries, they're written into the stream: /*save indices*/ for (i=0;i<nb_subvect;i++) {

Hi Jean-Marc, Hi Jim, I have also seen some problems with the 1.1.8 release on the C55x. So far I have boiled down the issues to the following: 1) We need our own "fixed_xx.h" header file. I don't know why, and haven't had time to investigate, but there is a definite improvement when I use the attached fixed_c55x.h file which has turned all the maths into inline functions.
