Whats the difference between a uniformed and non-uniformed histogram?

I am using openCV and am wondering about the diff between being uniformed or non-uniformed. Could someone give me a simple, NON-TECHNICAL des开发者_JAVA技巧cription?

Thanks

A uniform histogram has bins that are exactly the same size, For example a uniform historgram from 0-10 with 2 bins would contain the bins
{0-5} and {5-10}
Basically the histogtram is split evenly into a certain number of bins all the same size.

A non-uniform histogram will contain bins that are not of uniform size, etc, a non uniform histogram from 0-10 with 2 bins will contain bins like
{0-3} and {3-10}
Basically the historgram is split unevently into bins that are not the same size.
