WebSIFT vectors. The key point is that comparing RootSIFT descriptors using Euclidean distance is equivalent to using the Hellinger kernel to compare the original SIFT vectors: dE(√ x, √ y)2 =2−2H(x,y). RootSIFT is used in the specific object retrieval pipeline by simply replacing SIFT by RootSIFT at every point.
