Carnë,

Macro recording and macros in general are great for specific tasks
that can be applied to individual images, and are suitable for batch
processing. For complex programs I'd go for a language that makes
shuffling data around easy. For example python.

Here is a tutorial on using python with Fiji, an ImageJ distribution
packed with many libraries and plugins:

Hope that helps.
