Matching Experiments using SIFT descriptors

In this experiments we use Vedaldi's software. We provide the scale space and the software computes the points and descriptors. Then using the same sotware we match the points.

Matching using LB scale space

Matching using SIFT

We observe that the SIFT implementation performs better that the one using the LB approach. This is because the scale space we computed has different scales from the ones that are used by the implementation. Even we change the number of octaves and scales, internally the initial scale is not changed. The descriptors use this scale and it might be the reason the are badly computed.
