vxl is a third-generation class library for image processing, recognition, and analysis. The 2nd beta for release 1.0 is now available. It uses an interesting cross-platform build tool called cmake, which I assume is shared with vtk, the visualization class library from former GE researchers.
I would love to be employed in a commercial setting to leverage these open source frameworks. They are high quality, seasoned and mature packages. As far as I know their use hasn't broken out of academic or government circles. In time I believe it will, because although class libraries take greater skill to wield than a plethora of linear functions, if you're developing a competitive commercial product with no room for inefficiency, they really are slack.
