[R] Image segmentation

[Bryan Hanson]

I've recently had a reason to work a little with image segmentation too, and in addition to EBImage, you should look at biOps.  You can learn a lot by studying these packages.  Bryan

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
