You see lots of demos of this, I think because the algorithm is interesting but also pretty easy to implement.
As an approach it seems to do a decent job with either very small changes (e.g. slight change of aspect ratio) or uninteresting images, but aesthetically the results seem bad on most interesting images; I suspect because targeting "low information" regions of the image removes tension that is needed. Often a simple crop is much better, it seems.
