Neighborhood pyramid preserving hashing
WebOct 21, 2013 · Topology Preserving Hashing is proposed, a novel hashing method that is distinct from prior works by preserving the neighborhood rankings of data points in … Webreserving Hashing is to not only preserve the neighborhood relationships, but also preserve the neighborhood rankings. As shown in Fig. 1(c), TPH ensures that H(q1) and H(q2) are neighbors of H(p), and H(q1) is still a nearer neighbor of H(p) in Hamming space. Our method can be considered as a tight version of neighborhood-preserving and a loose
