Obviously if we'd use it in practice (in a web-museum ?)
all pic's matrices should be precalculated only once and
stored in a table with fourty fields v00 ... v93 like:

-----------------------------------------------
pic_title      v00    v01    v02    ...     v93
-----------------------------------------------
bears2.jpg    1234   4534   8922    ...     333
...
...
-----------------------------------------------

Then SQL query will look like this:

select top 3 pic_title from table
order by
abs(v00 - w[0][0]) +
abs(v01 - w[0][1]) +
... +
abs(v93 - w[9][3])

here w[][] is the matrix of a newly-entering picture.


P.S.
If someone will encounter 2 apparently unrelated pics
but for which ImSim gives value of their mutual diff.
*** less than 20% *** please emailed them to me.
