Hi Paritosh,
As mentioned earlier the mismatch is in the number of member variables
belonging to a cluster. Please see my email below:
"I managed to cluster my data using meanshift and then ran
clusterdumper, I get following output:
MSV-21{n=1 c=[1:0...........]
So I asssume that the cluster above has converged and n=1 indicates
that there is only one point associated with the cluster above.
Now I try to read the members of this cluster from "clusteredPoints"
directory. I see from the output that number of points belonging this
cluster is 173."
This mismatch persists even after using 0.6 snapshot.
Thanks,
Ipshita
