Hi dear gurus,

If the message doesn't belong to this newsgroup, I
am sorry - I tried my best to direct it to appropriate
ones.

I need to do some statistics different regions of an
image, the contour of the regions will be defined by
user with the use of mouse.

What I have done is I traced the movement of the 
mouse and generated a set of coordinates of the 
contour(s), but when I tried to calculate the area
within the contour(s), I find it very very 
complicated, at least for me.

Is there an established algorithm to do this? - also,
the contour generated by the user might not be closed,
is there also an algorithm to generate a closed 
contour?

Thanks.

Xiaoyi
