Hashing learning has attracted increasing attention these years with the explosive increase in data volume. Most existing hashing learning methods can be divided into two stages. Firstly, obtain low-dimensional representation of the original data. Secondly, quantize the low-dimensional representation of each sample and map them to binary codes. This two-stage hashing framework separates projection operation and quantization operation apart, and the original data structure cannot be well preserved after this kind of two-stage operation. Considering this, global similarity preserving hashing (GSPH) is proposed, which utilizes a joint hashing framework to directly project the original data to hamming space, and reduces the projection error and the quantization loss simultaneously. Moreover, GSPH presents a global similarity-based data sample reconstruction method, which describes the intrinsic manifold structure of original data more precisely. The image retrieval experimental results on Corel, CIFAR, LabelMe and NUS-WIDE datasets illustrate that our algorithm outperforms several other state-of-the-art methods.
