Abstract

The main drawback of SIFT is that the computational complexity of the algorithm increases rapidly with the number of feature points. In order to overcome this drawback, VF-SIFT algorithm was proposed. The formula derivation of speed up factor was researched and VF-SIFT was applied to SAR images matching in this paper. The experimental results shows that, the matching process is accelerated obviously and speed up factor fits in with the formula derivation.

Key words： SIFT; VF-SIFT; matching; speed up factor
