Java library to increase a picture's resolution
<p>I'm looking for a java library to use in my project that allows to increase the resolution of a given image.
Specifically, if it matters,
I'm working with android Bitmap objects.
Obviously, nothing like identifying the bad guy from a reflection on a guy's eye or anything, but I would like to take say a 50x50 picture and turn it into a 100x100 picture.
Obviously this isn't simple at all, but I'm looking for a library / API the will handle all the interpolation / algorithms for me.</p>

<p>It should preferably be simple to use, as what I'm looking is more practical and less academic / scientific.</p>
