Imagine a large matrix with dimensions [W,H], and a lots of smaller
matrices with dimensions [p,q1], [p,q1], [p,q2], [p,q1], ... I have to
slide a small window [p,q] horizontally over a larger matrix. After
each slide I have to compare smaller matrices with the data from larger
matrix (as defined b

I thought I should correct and clarify the use of EMSL (even though
this isn't specific toward your request, qvx.)

It's more for data format recognition and conversion. Here's a
description from the site. The sw was developed for earth science, but
is very usefu
I'm working on essentially the same thing for a real-time context. No
formal schema developed yet, but I know that I'll be using some
combination of the following: ADaM, ESML (Binary data format
unification...xml config), Numarray/Scipy, Pytables (DataBase), PIL,
Cairo (svg), and MatPlotlib.

I also have 0 OCR experience, but the case is simple enough.
I know about scipy but I have 0 experience with it. I was actually
hoping somebody who knows about it might have some recipe.
I also tried psyco, but unfortunetly, the speedup is only few percent.
I will check out ADaM's site.

Hi Take a look at ADaM's image processing functionality. I'd also
suggest seeing if Numarray of Scipy can be utilized.
Here's ADaM's site. I'm sure your familiar with the others mentioned.

Hi all,
I have a performance problem in my app. It is a poor man's version of
OCR app. I started this app as a prototype before implementing it in
C++. But now, after I have a working copy in Python, I don't feel like
doing the job again in C++. A speed improvement of at least 5 times
would be nec
