Need an advice

[Emmanuelle Gouillart]

Hi Nadav,

would you need everything to be faster, or do you have some identified
bottlenecks that take most of the computing time? In the latter case,
you may want to keep using the most standard tools for most image
processing steps, and pick a specialized and fast module for the most
critical steps, like OpenCV. Also, the algorithms in scikits-image
shouldn't do too bad in terms of executing speed, since they rely either
on numpy arrays or on Cython code: what speed factor would you expect to
gain with another library such as OpenCV?

As for alternative librairies, ITK is very powerful and fast and has
Python bindings. The learning curve looks a bit steep, though.

Cheers,
Emmanuelle
