Hello everyone, 

After trying multiple times to use Monterverdi 2.0 to run a classification, 
i got the same error : "Statistics cannot be calculated with zero relevant 
pixels". 

For more details, i clipped a pleiade image to minimize the processing time 
by a vectorial mask, and ran these OTB applications in this order : 
Compute images second order statistics > Train a classifier from multiple 
images > Image classification
The error appears while running the "Image classification".

To fix the issue, I already tried to change the vector data, to use another 
clipper application, to not use statistics from "Compute images second 
order stats" in the "Image classification" application. 

At this point I don't understand where this issue comes from and i didn't 
find any explanation on the multiples forums that could help on this field. 

So if you have any idea that could help me out on it, I would be really 
grateful. 

Dhersin Thomas.
