Semantic preserving hashing
WebSubsequently, we construct a bipartite graph to build coarse semantic neighborhood relationship between the hash codes and the class-specific prototypes, which can preserve the manifold structural information. Moreover, we utilize the pairwise supervised information to construct a fine semantic neighborhood relationship between the hash codes. WebI into a q-bit binary codes while preserving the semantic content of images. Although many deep hashing methods have been proposed to learn similarity-preserving binary codes, they often suffer from the limitations of either inadequate labeled training data or inaccurate semantic constraints. To end this, we propose to use the VAE-GAN
