RootsGLOH2: embedding RootSIFT ‘square rooting’ in sGLOH2

Abstract: This paper introduces an extension of the sGLOH2 local image descriptor inspired by RootSIFT "square rooting" as a way to indirectly alter the matching distance used to compare the descriptor vectors. The extended descriptor, named Roots-GLOH2, achieved the best results in terms of matching accuracy and robustness among the latest state-of-the-art non-deep descriptors in recent evaluation contests dealing with both planar and non-planar scenes. RootsGLOH2 also achieves a matching accuracy very close to that ob… Show more
