linking different processes in GUI

Hi,

I wrote a code that does various processing to the image. When representing them in a GUI it is not as straight forward as putting each process in diffent callback function.

So my question is how do I link the result of one function to the next one? i.e:

1st function: I read 1st image and apply so stuff to it, I extract parameters,

2nd function: use the above parameters and apply them to another image,

3rd function: call for a 3rd image and run some convolution the above too image

ect ...

Many thanks for your help in advance.
