Dear Milou,
Yes, this is expected : the fusion operation will take several
classification maps (i.e. 1 band image where each pixel holds the label
of the class it belongs to) and according to some fusion rule (dempster
or majority voting), it will find out a new label for each pixel (and
store it in classification map, i.e. a 1 band image).
What fusion does NOT do :
- Stack images (you can use ConcateImages instead),
- Fuse colored classification maps (i.e. if you transformed the
classification maps into a 3 band color image where each class has a
fancy color of its own).
Regards,
Julien

Hello,
I try to fuse 3 results of classification (using SVM classification in
monteverdi1.14), the result of both"majority voting and "Dempster
shafer fusion"" are in 1 band (in gray scale)! is there normal?
thank you.
