Hello,

Thanks for replying me!

I was investigating the EBImage package and actually
there is a algorithm for image segmentation. But I think this algorithm is not
automated enough for me and maybe to work with multispectral remote sensing
image when I want to segment the whole image. The algorithm does not look for
“seeds” automatically and I think there is not possibility to segment color
images.

I am looking for an algorithm similar to that
implemented in Spring software (developed at INPE) or what Multiresolution
Segmentation algorithm does in eCognition software (eCognition, 2012). This algorithm
was described by Baatz and Schäpe (2000).

Now I will see the second option that Susen sent me (http://www.itk.org/). But I would like something in R, that I can see the
script and in a language that I already know a bit. But the main reason of looking for something in R is the presence of other statistic tools not found in SPRING, eCOGNITION etc.

I would advise being somewhat more expansive when describing your requirements in future postings to this generalist audience. You might want to look at the CRAN Task Views: (first hit with Google if you search on that phrase). The Task Views used to be countable on one hand but now threaten to extend beyond a full page. I believe you will find the MedicalImaging or Spatial Views have pointers to tools with image analysis functions. The MedicalImaging View also has a link to: http://www.bioconductor.org/packages/release/bioc/html/EBImage.html
