title: How to merge a transparent png image with another image using Scikit-image
body: <p>This is basically the same question that was posted here: <a href="https://stackoverflow.com/questions/5324647/how-to-merge-a-transparent-png-image-with-another-image-using-pil">How to merge a transparent png image with another image using PIL</a> but using with scikit-image instead of PIL. I mean to paste the png keeping its transparency on top of a background image. Also, if there is actually a way of doing it, I would like to know which one is faster (PIL or scikit-image). Thanks.</p>
