Anyone have a suggestion for a library for adjusting contrast and for blurring images?  I was hoping to use ImageAdjuster, linked off of  http://processing.org/reference/libraries/, but the link [ http://www.davebollinger.com/works/imageadjuster/] now points to an advertisement for OpenOffice, and some quick messing around with Dave Bollinger's site doesn't seem to yield anything good.

I'd like to do blob detection on an image.  From reading the examples and playing, I can't yet figure out how to get OpenCV to look at anything other than a camera capture?  Any ideas?
