opencv used in web programming

edit

opencv comes with nice python / java wrappers already, also there's a heap of 3rd party ruby / php / node / c# wrappers (which unfortunately are mostly sparse and outdated)

but, - why not ?

hey Berak, Any example how to do it, for instance just add 10 + to the original image intensity? thanks

the answer probably won't help you(since all the context is lacking), but here we go:

Mat img;
img += Scalar::all(10);
