Interpolation strategies for Image Pyramid ORB.


When building a pyramid with the scaling level VX_SCALE_PYRAMID_ORB, which interpolation type should I use?
I think it’s quite implementation-specific question, so it may not be adquate to ask.
However, it will be okay even though you let me know that I can freely decide the interpolation strategy for ORB pyramid at least.



Also, is it able to build the laplacian pyramid using ORB scaling level?
If so, does it mean that I have to be able to “up-sample” the ORB-scaled image? (e.g., scale factor = 1/0.8409…)
