There are books on font identification algos for people to use - size and
bracket on n serifs, are the a or g double story, ratio of ascender to x
height in h, ratio of i stem, stuff like this - and PANOSE2 has a load of
this stuff. Font classification is a recent interest of mine, need to know
more about it...

What the Font indeed must work by analyzing bitmaps more or less using
the principle I described in my previous posting of subtracting a test
bitmap from a known bitmap in the database and looking at the
"residue" left over : less "residue" means a better match. It still
seems like a hard problem to me: First, in the case of a system like
WhatTheFont, you must have a good algorithm for aligning and scaling
bitmaps to the right size before trying to subtract one from the
other. Secondly, if you have a large database of bitmaps, just using
a brute-force approach to match the test glyph bitmap against every
bitmap in the database seems inefficient ... Ideally one would want a
way to create some sort of digital "fingerprint" from the full bitmap
that could be used as an index key for rapid retrieval of
closely-matched glyph bitmaps. Of course there have got to be ways to
do this. But, as I said, it seems like quite a bit of work to me ...
In fact, I wish I knew about some of the ideas for doing such
"fingerprinting" of similar images for the purposes of indexing, etc.
: Knowing how to do that would also provide a nice way to show a user
related fonts. Similar to what web sites like Amazon Books does, but
for fonts: "If you like this font, take a look at these similar fonts
