This question has really nothing to do with Gimp unless you want
to use already existing gimp functionality.
You may e.g. read an image into memory though the gdk_pixbuf
functions, and then access the pixel data through gdk_pixbuf_get_buf().
Working with the gimp API is more complicated as the data may
be stored tiled, and your algorithm will need to do special
case treatement of the boundries.
You might also want to have a look at GEGL that provides a
graph paradigm for image processing, and which will be used in
future versions of GIMP. Whether someone has written optimized
algorithms for it, I don't know.
