Yet another useless example for erlocaml, but this time it is not completely silly ... it does something :)
In fact the project eocarve uses:

• the ocamerl library (which got a makefile install rule for the occasion);
• the seamcarving library provided by mce (thanks!) (it's LGPL so the full code can be found in eocarve).

Idea is simple: an ocaml node run and provide a API for Erlang node to call the seamcarving library. See eocarve wiki for details/example.
Aim of this project was mainly to demonstrate use of ocamerl lib ... however it may be usefull for an Erlang web app which would need seamcarving (heavy weight for CPU!). Had fun to integrate those lib in same app.
