furry-parakeet: C kernels and wrappers for image combination

This repository contains the linear algebra and interpolation kernels used by PyIMCOM.

Installation

You should be able to pip install by going to the furry-parakeet directory and running:

pip install .

This uses the Numpy/C API. If you want to adjust the default settings for C compilers, you can edit setup.py (for example: openmp is enabled by default).

Legacy versions

Previous versions of furry-parakeet installed each file as a python module, so you would import with import pyimcom_croutines. You would now write from furry_parakeet import pyimcom_croutines. You can make code that would be compatible with either using:

try:
    from furry_parakeet import pyimcom_croutines
except ImportError:
    import pyimcom_croutines

Helpful information
