automated image processing
Hi, I am looking for a R package which is capable to process and analysis pictures of tissues (stained) in an automatic way. I had a look on biops and EBImage (Bioconductor) but they are not automatic... Did you already use/know a such package ? Thanks, - Martial _________________________________________________________________ Tchattez en direct en en vidéo avec vos amis !

Help with biOps loading
I have tried several times to load biOps package after reading the posts in this archive regarding the necessity of placing these two libs in the PATH (libjpeg62.dll and libtiff3.dll). I have tried locating the libs in several directories that should have worked, but I still get the following message. ------------------ Error in inDL(x, as.logical(local), as.logical(now), ...) :

Image Processing packages
Hi, I've been looking for Image Processing packages. Thresholding, Edge Filters, Dct, Segmentation, Restoration. I'm aware, that Octave, Matlab etc. would be a good address but then I'm missing the "statistical power" of R. Does anybody know of packages, projects etc. Comments on wether the use of R for such matters is useful are welcome. Greetings Thomas Kaliwe

Optional libraries (libtiff, etc) not found
I installed the (binary) biOps package, which can use libtiff and libfftw. Then I used macports to install the libraries (in /opt/local/lib). But I restart R and biOps still does not see the libraries. I've tried adding symbolic links from /opt/local/lib to /usr/local/lib, I've added /opt/local/lib to LIBRARY_PATH, LD_LIBRARY_PATH, and DYLD_LIBRARY_PATH, and it doesn't work. Do you

building biOps on macports, and configure--vars
All, the MacOSX binary build of the biOps package is broken on cran, so I am trying to compile from source. I am very close; the trick is apparently that this package depends on fftw3, libjpeg and libtiff. My fftw3 is in /usr/local/, but my libjpeg and libtiff are in /opt/local/ since i got them through macports. In general, I'd like to keep as many of my third-party libraries as I can in the

Package installation
Hello, I'm running R with windows. Could anybody help me how to install the package biOps (http://cran.mirroring.de/src/contrib/Descriptions/biOps.html) ? I cannot find it at any mirror provided by the GUI; I just found it as "tar.gz" which cannot be installed with the installation method... Maybe, I simply do something wrong? Thanks for any hint!

Análisis de imágenes en R
Buenas dias a tod@s, Quisiera saber si alguien tiene experiencia con el procesamiento de imágenes (en formatos JPEG o PNG) en R y la búsqueda de similitudes / diferencias entre ellas. La idea de lo que me gustaría hacer es: tomar una imagen, cargarla en R y luego analizar su estructura. Para las dos primeras tareas, la libreria ReadImages en CRAN me ha sido útil, pero para la segunda, hasta

Video Analysis?
What software exists for digitizing video to quantify the motion of specific features in the image? I might be willing to use something that's NOT in R, though I'd prefer something in R (or at least with an R intereface). Thanks, Spencer Graves

image color analysis
I am not sure if I should ask this question in this list. But I'll try. Currently I am trying to analyze images using EBImage and biOps. One of the features that I need to extract from various images is the color spectrum, namely, which colors each image consists of. So, each image hopefully can be converted into some sort of color histogram so that color ingredients are easily comparable

Rjava, RImageJ, and/or S4 question.

The following code starts the java imaging program ImageJ from within R, and displays an image (assuming ImageJ is installed on your computer). library(RImageJ) img <- IJ$openImage( file.choose() ) #pick an available .tif file img$show() # make the image object visible # An image is now displayed # find out about the objects involved >

Sobel's test for mediation and lme4/nlme
Hello, Any advice or pointers for implementing Sobel's test for mediation in 2-level model setting? For fitting the hierarchical models, I am using "lme4" but could also revert to "nlme" since it is a relatively simple varying intercept model and they yield identical estimates. I apologize for this is an R question with an embedded statistical question. I noticed that a
