Hello everybody,

I would like to know which of these ten methods (algorithms) belong to the global and which to the local threshold value?

![threshold](https://us1.discourse-cdn.com/flex002/uploads/slicer/original/3X/4/d/4d7eb12f5ebe5ca168c51f44ca3069f40507171f.jpeg)

The difference between global and local is not yet clear to me

Many thanks for the help

All of these methods use the entire image to compute the threshold value.
