Hi Paul, If the background is relatively uniform: Then a simple algorithm could be used, to distinguish foreground from background points. Essentially, returning a logical matrix.
Otherwise, I'm assuming that suitable pooling/convolution operations could be used for this purpose. Then you could estimate *relative* measures of height and mass from the logical matrix. (With more precise measures being possible, if you know the image scales). There are a number of R packages for reading images. Currently, I mainly use Simon Urbanek's package, "png". I'm currently creating a package with support for pooling/convolution operations, and related utility functions. However, it's not ready yet. Another option is Jeroen Ooms' package, "magick". best, B.
