Flagging outlier observations

[raf...@dotproduct3d.com]

Hello,

I'd like to know if Ceres can automatically "flag" outlier observations if a suitable robust cost function is used (Tukey, Huber).

If not, would I be able to accomplish this quickly by inserting suitable code into the implementation of

bool ResidualBlock::Evaluate() {}

in residual_block.cc ?

Or is there more magic involved and places I would need to consider?

Thanks!

There is no magic. You have to do outlier filtering yourself. I recommend doing it by using Problem::Evaluate.
