title: Otsu's Method and A Median Filter in Python
body: <p>I've tried looking around and have been unable to find any implementation of either Otsu's method or a median filter into Python other than OpenCV.These are the only two links of documentation for the OpenCV functions that I've tried.</p>

  <p>I checked this post first but it never really seemed to have a full solution that fits my problem.

  <p>I'm basically looking to see if anyone knows any other functions that I can implement both Otsu's method and a median filter. I'm just trying to find alternatives before I have to program them into myself, but I would rather not have to reinvent the wheel unless necessary. Thanks for your help in advance, if you need some more specific information just let me know.</p>
