Deep Hashing With Minimal-Distance-Separated Hash Centers

no code implementations CVPR 2023 Liangdao Wang, Yan Pan, Cong Liu, Hanjiang Lai, Jian Yin, Ye Liu

This paper presents an optimization method that finds hash centers with a constraint on the minimal distance between any pair of hash centers, which is non-trivial due to the non-convex nature of the problem.

ViT2Hash: Unsupervised Information-Preserving Hashing

no code implementations14 Jan 2022 Qinkang Gong, Liangdao Wang, Hanjiang Lai, Yan Pan, Jian Yin

Specifically, from pixels to continuous features, we first propose a feature-preserving module, using the corrupted image as input to reconstruct the original feature from the pre-trained ViT model and the complete image, so that the feature extractor can focus on preserving the meaningful information of original data.
