The Viterbi Algorithm - Illustrated!
====================================
This software enables the generation of illustrations for the Viterbi Algorithm
decoding of convolutional codes using Python.
A demo of the illustration created using this software can be found here_.
.. _here: http://veeresht.info/blog/viterbi-algorithm-illustrated/
Requirements
------------
- Python 2.7 or above
- NumPy 1.6 or above
- SciPy 0.10 or above
- Matplotlib 1.1 or above
- Cython 0.15 or above
- CommPy 0.1
Note: There are some modifications that need to be done in Matplotlib's **animation.py** file.
In subclass::
class ArtistAnimation(TimedAnimation)
comment the function::
def _pre_draw(self, framedata, blit)
as follows::
def _pre_draw(self, framedata, blit):
'''
Clears artists from the last frame.
'''
"""
if blit:
# Let blit handle clearing
self._blit_clear(self._drawn_artists, self._blit_cache)
else:
# Otherwise, make all the artists from the previous frame invisible
for artist in self._drawn_artists:
artist.set_visible(False)
