title: Histogram matching of two images in Python 2.x?
body: <p>I'm trying to match the histograms of two images (in MATLAB this could be done using <a href="http://www.mathworks.com/help/images/ref/imhistmatch.html" rel="noreferrer"><code>imhistmatch</code></a>).  Is there an equivalent function available from a standard Python library?  I've looked at OpenCV, scipy, and numpy but don't see any similar functionality. </p>
