I've made a fork on github to work on the opencv stuff: http://github.com/sccolbert/scikits.image I've also made a pull request to Stefan so the initial stuff will be available in the trunk. A large portion of the infrastructure is now in place with regards to array validation and utility functions. I think theres now enough to start aggressively wrapping functions. I haven't figured out a good way to build these modules yet. Making a setup.py causes Cython compilation to fail on the .pyx files, but using cython *.pyx and then compiling the .c files manually with gcc works fine... So it may be easiest in the future to just have the maintainer cythonize the .pyx and .pxd files, and only ship the .c sources, then have distutils build the c files. Cheers, Chris
