Hi there,

I found this maths notation and I don't understand the meaning of semicolon or dot in it. Any help would be greatly appreciated.

Please see attached image.

It looks like some sort of functional or programming notation.
What is the context?   Where did you see it?

I saw it on the paper. It was in an imaging paper. I have attached more part of the formula. Could you please take a look at it.

There is an explanation here:    http://en.wikipedia.org/wiki/Scale_space

But I can't claim to understand it entirely.
