I would recommend in this case that you use cython. It allows you to create a C implementation of your algorithm with a python front end, and compile it into an extension which you can then import into regular python code. If you use a numpy array to represent your image, it should work exceptionally well. There is a cython tutorial for using C code with python aimed specifically at numpy.
