Hello Julius,
Unfortunately, the functor you are looking for is indeed not implemented at the moment. Currently, I see two ways of handling this:
1. Porting SuperAverage3D
and other necessary functors into 2D, as you already mentioned. For this, it should be sufficient to copy the 3d version and remove the last dimension, you are right.
2. Trying the SuperLocalAverage2D
(see doxygen). This only limits the checked cells even further with a circle. However, a big radius will include your whole indicator and might work like a SuperAverage2D
.
If you need any assistance, please let me now.
Cheers,
Jan
