one typical path looks like this

- get familiar with the subject by reading your notes/books/papers...
- come up with an algorithm
- get ML
- read its docs re syntax/available functions/tbxs
- crank up ML
- read its docs re syntax/available functions/tbxs
- read its docs re syntax/available functions/tbxs
- implement your algorithm
- impress your cat/girlfriend/boyfriend/mother-in-law with a
- ...working solutions...

I don't think you can do it region-based interactively, only globally
on the entire image and for that you can use the intlut() function, or
simply fiddle with the colormap. For non-interactive, post-
