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.
