Interpolation strategies for Image Pyramid ORB.

Hello,

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.

Thanks,

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…)
