Hi Flo,
I want to ask you and Alex about the experience you have combining ITK
and OpenCV. Was it a success? Did you encounter some special
problems?
I would be glad to hear any information as I consider using the two libraries
in one project. OpenCV will be responsible for most of the processing and
except for image stitching and alignment which will be done in ITK.
Regards,
Tomas
# Hello Alex:
#
# Indeed, OpenCV is a bsd-like licence (refer to
# http://www.intel.com/technology/computing/opencv/license.htm).
# However, it changes if you link OpenCV to IPP, that is the Intel "Hardware"
# specific libraries making the most of Multi-core, Multi-CPU. It is no more
# BSD in that you need to Pay for a licence, even for the case of academic
# researches.
#
# What I recommend (and let me know if 'm wrong) is thus to develop, if there
# are any benefit, with ITK+OpenCV, and let who wants (including oneself) to
# integrate IPP - It does not change the ITK+OpenCV source code in any ways.
# So that BSD-feeling is kept intact, source code can be shared ... and for
# performance one can simply include the IPP or anything comparable
# a-posteriori.
#
# We'll stay in touch to see how feasible is such thing.
#
# Flo.

# Hi Flo,
#
# I am also interested in speeding filters up (muti-threading, clustering?).
# My architecture is quite similar to yours: Linux/BSD with multi-CPUs.
# And I am concerned about license issue. Correct me if I am wrong.
# I thought OpenVM is a free open-source software with BSD style license.
#
# It is not?
#
# Thanks,
# Alex
