[mlpack] Basic advice needed

[Andy Green]

Hi -

I am interested in using mlpack for a task involving identifying 
characteristic areas of bitmap images.

What I hope to do is feed it the images and for teaching purposes, show 
it where the characteristic areas are with a second image highlighting 
them, and eventually have it use this information to be able to estimate 
by itself where the regions of interest are.

It's along the same lines to face recognition, but it's generic 'areas 
of text' recognition.  It's not trying to understand the text, it needs 
to group the areas with contiguous text with a polygon or 'heat map'.

I should be able to use the C++ library OK but I have no clue what 
algorithm or general gameplan to apply.

Any advice gratefully received :-)
