R help - Apr 2010 - Image RGB calculation

Dear all,

I need to read an image (mostly jpg) and split the channel of this image to
an colour channel calculation like this:

sqrt(R?+G?+B?)


Do you have an idea what package I need to use for it, and is it possible?

Thanky a lot

Ole

For general image processing capabilities within R,
I would recommend the EBImage package which you can
find on the BioConductor repositories.


Hope this helps,
Tobias

Thanks a lot, i will try this out!
