thanks everyone,
in fact, i already start with the tutorial http://www.imagemagick.org/Usage/masking/#bg_remove
the point i could not do is to create the mask as described in the tutorial :

convert difference.png -threshold 0 boolean_mask.png
convert cyclops.png boolean_mask.png \

thanks a lot !!

thank you. Any idea on how to make it black ?
