Hi,
I think, you should apply some kind of linescan of rounded coordinates
of your scatter gram, so you would determine the first "fit" and the
last "fit" within a scanned line (column or row) with your rounded
data points, determine for each fit within the line its nearest
neighbour and store them. Then, you scan the next line and so on.
After this you can connect your stored points by computing lines
between the points, round the coordinates of the lines, sort the
unique entries and store them and so on... Maybe it's a typical
clipping problem which can be combined with some nearest neighbor
approaches...

Only my 2 cents

Regards
