There might be a way doing that in R, but if you really need to take measures of a picture in some standardized way, I suggest you take a look at ImageJ. More than R that seems the right tool for the job. Some people have been experimenting with connecting ImageJ and R, but even without connection a simple text file can get the data where it has to be.
