Spherical hashing
Web'We present an efficient and fast algorithm for computing approximate nearest neighbor fields between two images. Our method builds on the concept of Coherency-Sensitive Hashing (CSH), but uses a recent hashing scheme, Spherical Hashing (SpH), which is known to be better adapted to the nearest-neighbor problem for natural images. WebExisting hashing techniques encode high dimensional data points by using hyperplane-based hashing functions. In this paper we propose a novel hypersphere- based hashing …

Webs include Iterative Quantization (ITQ) [9], Isotropic Hash-ing (IsoH) [17], Spherical Hashing (SpH) [12] and so on [25, 19, 24]. In these methods, rather than randomly gen-erated, hash functions are learned from data distribution or supervised information. The learning process is driven by a core principle, i.e., similar samples in the original ... WebFast Approximate Nearest-Neighbor Field by Cascaded Spherical Hashing I. Torres-Xirau, J. Salvador, E.
