Thanks. I tried EBImage several years ago for another problem, but Bioconductor packages have some difficulties to install in our network/firewall environment and I am not in a position to change it. It seems to me also an overkill for such simple task.
jpeg and png seems to me a bit too much simple, without direct possibility to transform from rgb to grayscale and normalisation. Anyway, I will give it a try.

Basically I imported image to R, changed rgb to grayscale, normalised an image made some selections and changed to image by imagematrix. Recently I learned that this package was removed from CRAN and can not be used in R 3.0.0. What options I have now to import image to R, change it to grayscale, make some computation or selection, change it back to image and plot for visual inspection.
