Rotation invariant daisy

[mpkuse]

Hi,
I came across your paper on rotation invariant daisy, in addition to the original one.
Fast Rotation-Invariant DAISY Descriptor for Image Keypoint Matching ...

I am wondering how can I test code for rotation invariant.

Is it possible to enable the rotation invariance in this code? Or is it implemented in another code base?

libdaisy/src/main.cpp

Line 234 in e880e0a

// if( rotation_inv ) desc->rotation_invariant(orientation_resolution, rotation_inv);

What is your suggestion on this?
