Easy to use Dynamic Time Warping in Cython. You can set your own distance in
_example_dist.pyx by respecting the function name and the type.
Dependencies:
- Cython
- Numpy
- (optional) Matplotlib
Use/test:
(optional) cython -a dtw/_dtw.pyx && open dtw/_dtw.html
python -c "import pyximport; import numpy as np;\
pyximport.install(setup_args={'include_dirs':[np.get_include()]});\
import dtw; dtw._dtw.test()"
Install:
make install
See dtw.DTW(...) and dtw._dtw.test() for the usage of the DTW function.
I keep DTW_a and DTW_f separated to be able to restrict the search (by a
maximum warp or a heuristic) in DTW_f, while I can experiment with parallel
computing of the dist_array for DTW_a (on GPUs).
