[RESOLVED] Little help with formula pseudocode

[Greyskull]

thanks for the replies and point me in the right direction, i kinda had that idea from this:

http://www.efunda.com/math/settheory/settheory.cfm

but i guess i misunderstood what theyr saying :S

To jemidiah, i wanted to use this formula to do some region segmentation in an image. S = total number of regions in an image.

As for your pie example, i get the fact that each pie has diffrent crumbs but i dnt c d relation of this to the empty set :S sorz...

Additional info: To make the formula wrk i must ensure that if satisfies the following conditions:

H(Ri) = True, i = 1,2,3,.......,S -> i fink i get this bit
and
H(Ri U Rj) = False, i != j, Ri adjacent to Rj

Thanks in advance
