[seqfan] Graphical recognition software, anyone?

Dear Sequence Fans:
If you go to a sequence in the OEIS and click "graph" you see two plots.
The lower one is a scatter plot that typically shows you 10K terms.
Could we use facial recognition software to classify these plots, and in
particular to look for the best match to one we are trying to analyse?

The plots of existing sequences would give us a database of say 100K plots.

(Our plotting software - which uses R - automatically produces a log-plot
if that seems appropriate. But that's fine, we just look for a match to the
log-plot.  If the sequence has a b-file, typically 10K or 20K terms, that
is used for the plot.)

For example, I was just looking at these 4 related sequences,
A267099, A351168, A351430, A351436.  It would be nice to be able to call up
a program that would simply look at all the plots of the OEIS entries, and
find the closest matches to them.

Can we turn spyware into sequence-ware?
