I was wondering if anyone could help me with this rather arbitrary math problem.(adsbygoogle = window.adsbygoogle || []).push({});

I need a description of what a gradient is in mostly non-math terms. I know a gradient is a sort of slope, but I don't understand where you would draw the line of what is and what is not a gradient. Meaning which slopes are and are not a gradient. Is this even calculable? I know http://en.wikipedia.org/wiki/Gradient" [Broken] on it has some equations but I don't understand any of that.

I am using this for an image processing project where the maximum pixel intensity value is 765 and minimum is 0. So for example is a sequence of pixels with the values 10,15,20,25 a gradient? I'd think so, but is 9,16,21,24 also a gradient? Where do you draw the line between gradient and non-gradient?

Thanks a lot :)
