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. WebOct 28, 2024 · Spherical hashing [15] is a hypersphere-based hashing method and groups the spatially coherent data points into the hyperspheres. Graph-based hashing methods [12,13,14] learn the hash functions from the graph which denotes the similarity between any pair of data points.

WebSequential Projection Hashing [2] - In this paper, we develop a data-dependent projection learning method (similar to the concept of boosting) such that each hashing function is designed to correct the errors made by the previous one sequentially. 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 ...
