I think that the package  AnalyzeFMRI (see CRAN) is dedicated to the analysis of
magnetic resonance Imaging
via some modelling with splines and Fourier transformation. However this package
seems not to be for the
image preprocessing. In general the definition of noise in image is depending of
the underlying modelling.
There are certainly many methods of images segmentation which are not included in
R.
Perhaps you can use if it exists in R a package based on mixture
modelling and use the threshold.of the corresponding histograms in order to
discrimnate signal from background.
I think that there is many other solutions which can be easily used for that task.

Best regards.
