Ok, I just fixed the gridflow anonymous cvs, which has been down since 
monday evening, because I had to reinstall artengine.ca and forgot to 
reinstall it. (However, this disabled the non-anonymous cvs and I have to 
figure out why)

The GridFlow page was down from Monday to Wednesday for other related 
reasons, but if you have tried today it should have worked. Else could you 
please send me more info about it?

It should be working right now. from extra/, do:
mkdir gridflow
cd gridflow
export CVSROOT=:pserver:anonymous at cvs.gridflow.ca:/home/cvs/gridflow
cvs login
cvs checkout .

For each blob it outputs one scalar for the number of pixels in the blob, 
a vector for the centre of the blob, and a matrix for the variance of the 
blob. The variance can be turned into a standard deviation made either of 
xx, xy, yy components (cartesian), or long radius, short radius, angle 
(polar), if you use appropriate math objects. After sending this for every 
blob, it outputs one blob in index colour where each blob has a different 
colour and the background is 0. The input must be a binary image made of 
only 0 and 1.
